Physical Shifting

P-shifting, physical shifting, the most sought after and most difficult shift to perform.

P-shifting is the final step, actually, physically becoming who you truly are.

P-shifting can take months to years to learn how to control, let alone shift on command.

Even I, Comet, cannot control my shifts. But, as always, i've compiled methods from some of the most well known p-shifters to go here, and their sources. ​

Before we start, the links to the majority of the methods: (all are backed up in case of deletion)
1.Blaze's "School of shifting" Website with many exercise to learn to control shift
2.The shifting database
3. Pariah pack's masterpost ​

Now, onto the actual methods. ​

Comet's P-shifting Method

My personal p-shifting routine, simplified as I don't know how else to really word what I do.
Step 1: Get into a comfortable, animal-like position in a dark room.
Step 2: Meditate. Visualise yourself laying there.
Step 3: Mental flare and Phantom shift, just for the hell of it.
Step 4: Tell yourself "I am a dragon (or, whatever your animal is)."
Step 5: visualise your body changing and push all of your energy to each part. Feel everything. Know everything. This is natural.
Step 6: Continue, keep feeling, changing, and pushing. Do not open your eyes.
Step 7: When you feel as if you have p-shifted, open your eyes. Check your body for any changes, like discolouration, scales, fur, etc. If you find any, great, keep pushing next time. ​

Blaze's P-shifting "Handbook"

The big guns, the most well-known modern p-shifting method. Use with caution y'all.

Here it is, the method that I use, and I will go in to as much detail as I can, so that you might get the most reference out of it and have less questions so that you can just straight off shift.

First off, you need to understand that there is a very complex science behind this. No matter what you do, you cannot escape physics. But even with the "limits" of physics, even some amazing unbelievable things can happen. I will answer a few questions that I am commonly asked.

FAQ:
Q: Do you get bigger or smaller when you shift?
A: No, it is not physically possible to change in size in the quick shifts I am going into, and wolves have the same ranges of body mass, so it is unnecessary. The law of conservation of mass states: Matter cannot be created nor destroyed in a chemical reaction. This means that you cannot change in size unless you find a way to draw on a source of matter, and as far as I know, there is no way.
Q: What happens to your clothes when you shift?
A: Well, most prefer to remove their clothes prior to shifting. If you do not, you will simply have to find a way to remove your clothes when you are in wolf form.
Q: When you shift, do you become a full wolf, or a hybrid?
A: As far as I have seen, everybody becomes a full wolf, but in a partial shift, which is a rare incident, or can be performed voluntarily by terminating a shift while in the transition (which is quite a bit harder than it sounds) will result in a partial shift, which will leave you in whatever hybrid stage you were in at the instant of termination. You can also shift individual body parts by only focusing on them.
Q: Is there a limit of time that you can remain in wolf form?
A: Technically, yes. Each person's limit varies on how much practice they have had. The reason for this limit is because the longer you remain a wolf, the deeper established your wolf form becomes, which means that it gets harder to change back the longer you remain in wolf form. The consequence of exceeding the time that you can power is simple: you lose the ability to change back. You basically get "stuck" as a wolf for the rest of your life, or until you can overwhelmingly pull through (rare). This point at which you should not pass is called the point of no return. Usually for a beginner it is about an hour, however for very experienced shifters, it can extend into a week. Never pass the PNR. That is an important warning.
Q: When I shift, will I still have my human mind?
A: Yes and no. Yes you will remember everything, and be in control. No, your mind will be quite changed. You will have the deep end of instincts and heightened senses as well as reaction. There is a certain situation that can cause you to temporarily lose your entire human function. That is called "possession". It is when your mind rejects it's human side entirely. There are 3 degrees of possession. 1st degree: Short loss of humanity (up to 1 minute), 2nd degree: Temporary long loss of humanity (1 minute or longer), and 3rd degree: permanent loss of humanity (permanent). Possession must be predicted before it occurs, because if you reach 3rd degree possession, you will have absolutely no human left in you. To predict this incident before it happens, there are symptoms you should be aware of: inability to control M-shifting, short attention span, overwhelming wolf instincts, occasional feeling or desire (like an addiction) to shift into a wolf, involuntary P-shifting, extreme loss of energy during p-shifting. If you have any one of these symptoms, be cautious that you do not lose focus while shifting, if you have more than 2 of these symptoms, you will very likely become possessed if you lose focus during a shift. This high risk can be reduced by practicing focus. It will always be a danger though.
Q: Can you become an animal other than a wolf?
A: Some of them, yes. Others require long term shifting (I don't describe it because it is unnecessary to become a wolf, and it requires total loss of ability to change back.) The ones that do not require long term shifts are the ones with same mass range as us (they can weigh the same as you)
AND LAST BUT NOT LEAST, THE ONE THAT I GET ASKED MORE THAN ANY OTHER QUESTION: HOW TO SHIFT

I will describe the method for all forms of shifting. By popular request I will include not only rapid shift, but my general concept of long term shifting. If you know an animal form eligible for the rapid shift, then substitute the word "wolf" with "_whatever your animal is_"

There are 2 classes of shift, M and P. As you might already know, M-shift is Mental shift, and P-shift is Physical shift. The M-shift is where you induce instinct, thought pattern, and the base around which the P-shift is built. The P-shift is the actual change of the form of the body. There are 3 different subclasses of P-shift. They are Practice, On-Spot, and Long-Term. Before any of these, you must achieve an M-shift, and then, the first subclasses available are practice and long term. After practice, comes On-Spot, which is the true mastery of the P-shift. Long term is not a mastery, but a commitment. If you long term shift, you will never again be human, and once you have unlocked it, there is not turning back. Now that I have covered the basics, we are ready to proceed to the instructions, starting with the M-shift.

Warning! Shifting is a life change, it is not something to mess around with. Certain parts and consequences are irreversible. Do not attempt unless you are absolutely sure of what you are about to do. I reserve no responsibility for any action that you might take. Be aware of my warning. This REALLY WORKS when performed as instructed!

To M-Shift, there is a thing I like to call the 3IA of M-Shifting. Inspiration, Investigation, Imagination, Application. Those are all the steps to a successful M-Shift. Inspiration: You need to inspire yourself. Keep some pictures or other representation of a wolf nearby or with you at all times, and try to keep yourself thinking of wolves nonstop. At around the same time, you need to Investigate. Investigation: You need to find as much information about wolves as you can, and quiz yourself. Make yourself as much of a wolf expert as you can. After you are an "expert" you need to use all that knowledge you gathered and imagine it. Imagination: You need to draw on the behavior, minds, and instincts of wolves, and simply imagine yourself (to the point that you believe it) as a wolf, but not physically, mentally. Continue doing this until you are not only a wolf enthusiast and expert, but also a wolf at mind, so much that you feel that you are one at points, this means that the wolf side has taken over your mind. This is not a switch on and off thing. The M-shift is permanent, but it can be controlled so that you can fit in in human society. Once you M-shift, your mind is set on a permanent course becoming a wolf mind. It is irreversible, and can be set off involuntarily. This will definitely change you forever.

The next stage I will talk about is the Practice P-Shift stage. The alternate stage that opts-in here is the Long-Term Shift, which is 2 paragraphs down. The starting point of the practice P-shift is completion of the M-shift. Once that is complete, you must once again draw on the expert knowledge that you obtained in the Investigation part of the M-shift. You need to be able to picture the physical aspects of a wolf, AS MUCH AS YOU CAN POSSIBLY GET, and bring it to mind again. You must then use the skill gained in the Imagination part of the M-shift. You need to first fire up that wolf mind and relieve all restraints and "release your inner wolf" in a sanctuary (somewhere that you can be alone, relaxed, and free of all distractions.) Then you need to get relaxed as deeply as possible, and gather as much focus as you can on what it would look like and feel like to be a wolf for a second, now, fire up that wolf mind all the way until you feel you are a wolf again. Now, imagine your human body as "what I would look like IF I was a human" and work from that, and how it would feel as a human, and what it would look like, then work on to what it would feel and look like to shift into a wolf. Imagine it as VIVIDLY as possible using all senses. Keep practicing, it might not work the first time, I also recommend focusing on one body part at a time as you practice it, because you will get individual parts easier. Eyes, teeth, ears, paws, those are the easiest few. The tail comes in just after these. Work towards your end goal with PATIENCE. If you are impatient, you will not get any results. Usually a full shift takes 2 weeks to 4 months to achieve. It depends on the concentration of wolf blood in you, the more you practice, the more concentrated it becomes. You definitely don't want 100% though (that only happens after PNR, and 3rd degree possession). Once you achieve a shift, I call the point at which you shift, the barrier. The barrier is also called the "sneeze" by some, because the nature of the barrier is exactly like a sneeze. It begins with a strange sensation that rushes across you, and becomes a burst that you cannot control. When you reach it, you will feel a sensation like a cozy warm feeling, then a feeling of energy surging through you (not painful), that soon becomes a feeling of clenching and flexing all over your body, and a strange feeling that everything your body is made of is changing. During this, your body involuntarily moved as if you are being controlled, and it leaves you helpless to control your own body, this barrier lasts anywhere between 5 and 50 seconds. It is important that once you reach the barrier, you do not panic, or you will terminate the shift, and nothing will happen. You need to just be relaxed as a rock and let the shift take it's course. Once you do, you will become a wolf. So at this point it is important to know how to shift back. In the first few shifts, falling asleep is usually enough to end it, but if you aren't tired, remember that staying a wolf on the first few shifts for longer than an hour can result in PNR passing, and being "stuck" forever. So the other method is to P-shift back, imagine yourself returning, you might need to use more strength and focus the longer you stay. Be aware of that. It is a more simple reverse method of P-shifting to turn yourself back.

After the Practice shift, you are ready to work on the On-Spot P-Shift. Take note that this one is the one with the highest danger factor for those with possession. In this one, you just need to practice fully flaring your m-shift, and focusing hard enough to induce a full shift while you are not in controlled circumstances. Best methods of training involve doing this while standing up. Practice avoiding distractions, flaring your focus, flaring your M-shift, and quickly P-shifting. It is important to emphasize focus, and dropping your humanity to the point you know you are a wolf on a moments notice. String everything together and practice to P-shift on a moments notice in a distracting and stressful environment. That is the On-Spot shift.

***This is long term shifting, it is the shift that you can never return to human form, which you can use to become almost any animal, it is not recommended. DO NOT EVER ATTEMPT UNLESS YOU ARE READY TO GIVE UP YOUR ENTIRE HUMAN LIFE FOREVER. Now that you have been warned, this is just a concept, I cannot guarantee it works, because anybody who used it is no longer a human. The data I compiled is well passed in archives. It is not a common one, but under study, I find that it could work if performed properly. The Long-Term shift is long term in 2 ways. It lasts until you die, and it takes a relatively long time to be complete. First, you need to have some form of that animal's genes in you somewhere, and they must be in an active cell. You just repeat the actions in the M-shift, and Practice P-shift, but in the practice P-shift, you must focus day after day, and expect very tiny results. Eventually it will set you on a frictionless course to permanently becoming that animal. This one can work for animals of different masses, because the time frame allows you to gain or lose significant amounts of mass. This one is absolutely irreversible and inevitably results in possession.  ​

Like Blaze, super popular and useful methods.

The P-shift:
Before you read this, please note that I will not be responsible for any problems occurring in the shift, or if anything happens to you. This is how I shift and its to help Wolfs who cant or to improve it.
Lay down (I don’t know how to spell lie) in a spot where you feel like you can be yourself, relaxed, and away from distractions. After you do that, I use what Blaze does; Think of your human body and note it, the way the bones are, how the muscles feel, the fur-less skin, and think: this is what I would look like if I was human, and then think of your wolf… The eye color, the fur, bones, muscles….etc. Think of the way your mind works, and feel your snout. Smell better, see better (I have my eyes closed) and feel better. Tell your self “this is me, and I’m glad I am” when you look over your wolf. Feel the paws and joints, the claws, and the fur as immensely as you can. The M-shift will naturally grow stronger when you are doing this, when get dizzy and loose thinking a little, this is normal and if any spots are/get sore, encourage them, but when you picture your body, don’t “look at them” as such, like have all your attention focused on them, just Acknowledge that that’s there. Feel the wolf, and you should get that weird but nice feeling. But remember when you try this STAY STILL. I didn’t really do that that well when I tried the first couple of times, I would scratch an itch every half hour, that will stop the shift (well, it does for me anyway), now, well lately, after my first shift, I stay still. It gets you there.
Like blaze, my first shift was a full body shift, and I blacked out but I knew because my room was a mess, and my bin (luckily paper, since I had gone through it, yuck!) was split all over my room… I had a massive as job to clean up my room.

Now here is the As-If-I-were-you version (but please know I means you, since we all call ourselves I):

I lay down, and relax my breath… ten seconds in, ten seconds out. I focus on my human body, and search for any tightness and stress…. Releasing those, I relax. I think “you are sinking into cement; you’re body, head, legs, arms, are all heavy… (This relaxes you like hell!) Then I go into meditation: I try not to think, my mind is black… I may see thoughts. I Acknowledge them, know their there, and let them go. I am nothing, just my breath…I walk into a house/forest (I prefer forest), I walk through it, noticing the things I like. I pick my favorite room/spot I like, if it’s a room; theirs a chair. It can be any chair you want. Go sit in it, and relax. If it is a forest, your favorite spot can have a rock covered in moss or pine needles (for me, its gum leaves, and the smell of eucalyptus) covering the ground, making a soft bed. Lay down, and too, relax… (You can do that If I was a human before too, if you want) You are no longer a human, you are a wolf. Feel the fur, claws…etc. If anything starts to hurt, notice them, and encourage them. But don’t look at them. When I feel the pain, instead of looking for witch part on that human body it is, my back paw is hurting, my muzzle is throbbing etc… I start to get dizzy, I can only think of one thing at a time, but that is what I am thinking now, there are no back round thoughts… My body starts to move on its own, and I get that great soft pins and needle-ish feeling, it goes through my whole body… I open my eyes… My (insert color here) eyes.

I hope I can help lost of P-shifters-to-be out there to shift, and I wish everyone who tries my way the best of luck! And everyone else s way as well, but I found that I read heaps and constantly modified my shift method, so I didn’t shift due to the fact that the way I shifted modified/changed every time. My body couldn’t take it. So when I settled down and stuck to 1 shift method, I shifted. It was a full body shift, but I blacked out. I knew in the morning because I was sore all over and I had extremely heightened senses. If that happened to you, don’t talk yourself out of saying that you did it, because you would have. At the moment I am attempting to shift into a dingo since they are native they are easier to shift into for me (so far I’ve been getting results quicker than what I try as a wolf) I mean, yeah I want to be a wolf more, but this is to get me started and better. A Dingo is basically a wild dog, and my m-shift is that of a wolf. I think it is easier to shift into the were animal that is native to your aria, But I intend to go back to wolf after I have sort of mastered the dingo. Wolfs are bigger, and more wild and un-tamable creatures than the dingo. ​

Icy's Handbook:

First off, I would like you to know that I have only fully shifted around two times, but I have done some in between things. I, and I have discussed the same thing with another member, like to think the mantra "I'm a wolf" now and then while P-Shifting. You have to be fully relaxed. Some of the pack members says being in water helps. Don't tense up. Imagine your self shifting, and really feel all the details. M-Shift before you P-Shift. It doesn't take just one night, practice and belief make perfect. If you feel you are upon a shift, DON'T QUIT. On one of my very first nights of practicing, I actually got really far! But I was thinking 'Oh, I can do it tomorrow! Heck, I have my whole life!" because the feeling really is shocking, and quit frightening. Since then, it has been very, very hard to get back to that state and I regret not continuing. If you get to a black, empty, float-y feeling, and your numb-ish, that's good. You might feel your thoughts slipping away and feeling very distant. It's a scary feeling. Urge that feeling. That is your humanity leaving. And I do recommend to urge any sensations, numbness, and even, pain. One way to know your on the right track is if you feel sore or start to twitch a lot. Those are beginning results. Also, if you feel this prickly "layer" between the sheets, bed, whatever your laying on, your getting the results of fur, which is very good. Really, I am hoping for the handbook soon from Blaze. He has pages of information, all the information we'll ever need to complete a shift, he says. But whenever we ask, he disappears, I guess. I hope he sends it out soon. You have to believe 12536647567567% and more. If you don't, you won't. Basically all the methods on the other sites are good, but I will try to help you out.

You'll have to have a good sense of visualization and mental concentration. Remember, don't get distracted, concentrate, believe, yes, it is to good- but it is true. Just keep M-Shifting, and get into that mindset before you attempt a shift. It will help. Be fully relaxed in a calm, dark place. Become relaxed. Once you are all comfy, don't move. Freeze. Become numb. Concentrate on your wolf self and the feel of it. Imagine your body clay, and you mold yourself into a wolf. Feel the pain. Encourage any pain, twitches, numbness, or sensations. Even dizziness. You might feel sudden snaps in some places of your body where bones are; your spine, neck, legs. Imagine, feel, a throbbing ball of energy in your chest that spreads through your whole body, transforming yourself into a wolf. Draw and write every detail of your wolf self, too. On one of my first tries I got here, and I freaked. I was scared and excited times ten. I thought, well, I have my whole life to do that again and I'll just think it over for now. So I was so happy I almost shifted, but then it took me forever to get back there. So if you get somewhere, don't procrastinate, don't panic, don't back out. Do it. Keep going. It will all work out and the results will change your life.

Vital notes: On the front paws, there is four toes. Then there is sorta a thumb, then a dew claw. On the back paws, there is only four toes. We have five fingers; poof goes your pinkie toe. Feel fur immensely.  become Inspired. Don't give up. Believe, Believe, Believe, Believe, Believe,Believe,Believe.

As I say, dear moon, belief is key.  ​

Fame_White_wolf's method

P-shift

P-shift or physical shift is when you actually transform into your were(animal) . Now to explain how this shift is going to work . First there is that law i mentioned above (conservation of matter and energy), all that your new body is going to have must come from your old one ,you need to expand energy to shift. Note - what size you are in human form that size you are in wolf form or i must say again that difficult sentence conservation of matter and energy :’( .Second thing is that you are going to shift bones etc, so you are going to be loud make sure no one is in your house or that you are in some soundproof room.OK now lets get back to the actual shifting J. So by now you finished m-shifting and now you are laying in your bed and want to p-shift, this is what you must do . First relax yourself because when you hit the barrier (explained later on) your body will move by itself , here’s a tip how to relax, when you lay on your bed(recommended)   or wherever you are, do this, say and do the following to yourself : 50 breath in , 50 breath out ; 49 breath in, 49 breath out etc. . Now when you are relaxed make sure that there is no noise around you, make sure that there is minimal noise because if you lose your concentration your shifting will stop. Next you need to flare your m-shift ,just deny that you are a human and let go of your human feelings and let your animal mind take control. Now to start p-shift you need to do any of the following: imagine yourself as your were(animal) very vividly and try to keep that in your mind as long as you can , imagine your were(animal) spirit entering your body and changing it , try imagining yourself in human form while denying being human then imagine that your body is made of clay and it reforms into your animal form. Now when you hit the barrier try not to lose your focuser you will break the shift process and nothing will happen , your body will move on itself , your muscles are going to realign , your bones are going to realign and break  they will move in certain pattern that allows you to stay alive during this process  and after that you will become that fur animal J (wolf) or whatever animal you wanted to become .                                               

Most important thing that you need to know: to shift you need from one week to month on perfect conditions but lets face the facts nobody is perfect , one night you will say oh I'm too tired , on next night you will say i can do it tomorrow its not like its going to run away (lol) , well it's going to run away if you keep doing that , then after that you will face something that most of us been trough you will start to question our existence and your faith in shape-shifting will be put to the test that’s where you must be strong that’s where many unfortunately quit!  If you pass this you will believe in yourself and into shape-shifting like never before but you will still need time to complete shift!
Note! – it is possible that your m-shift faded(rare) so all you need to do is to start m-shift again but it will be much 
Note  - don’t expect to shift on the first try , you will have to practice alot !
Note   - first time you will probably black out before you shift or if you lucky maybe after the shift but don’t worry you are expanding your energy it had to happen .
Note   - when you shift first time you can only stay in your wolf form a few hours usually maximum 2 if you pass this you will stay wolf probably forever this is called point of no return or PNR , you will probably break the shift by falling asleep.

Some other things
Here are some other stuff i think i need to mention. If you are asking yourself what is that long term shift that allows you to become a very large animal J well i don’t know much about it , all i know is that it is easier that regular reversible shift , that you don’t need to m-shift before you become a wolf and that once you shift you can’t take your human form anymore :’( . The guy that knows something about this type of shift is the guy that we owe everything it used to be a alpha male of the Razgriz pack named Blaze. He isn’t with us anymore so long term shift is going to be a mystery for us for a while :’( .
Next there are two types of were animals , first are naturals the one’s that shifted without any practice in them is a highly concentrated were blood at least that’s my opinion , and the others are the one’s that achieved it trough practice. ​

ADSTER'S GUIDE TO SHIFTING

The main thing that will get you to shift fast is believing with all your heart and constantly thinking of it. You have to have a passion, and be determined. Instead of saying "I'm going to be a werewolf" or "I'm practicing becoming a werewolf" say "I am a werewolf" often. Instead of seeing in the eyes of a person see in the eyes of a wolf. Imaginary you are one, not becoming one. This takes belief, but is possible with much determination.

When you want to shift don't go sitting for hours practicing your shift. And don't stress over it. Here are a few tips for shifting:
1: Just lie down with arms and legs spread out wide.
2: take a couple of deep breaths and imagine you are heavy (it calms you down a lot)
3: Imagine a duplicate of yourself. Then watch it transform into a wolf. Then give it a ball of power. Ask it its name. It might not respond the first time. this is normal.
4: now that you have done that image you are a wolf running free. Do things a wolf would.
5: Imagine each body part shifting. morphing. changing. Then imagine the whole body.
6: be free. be a wolf. imagine the wolf. imagine the change.
7: Soon you will feel change. Don't panic. Be calm.
8: Now your done. Do this as often as possible but don't spend TOO much time on it. You will get stressed over it. ​

Lilark's Method:

P-shifting is usually ALOT harder than m-shifting, and takes ALOT of practice.But cannot be done without first M-shifting

Sit or Lye down in a comfortable position. Let the silence take hold of your mind. Breath in and out slowly, If you start to get aches and Tingles, this is good. Focus on the parts of your body that have the most about of numbness or tingles. You may also feel a bit of pain, or hear bones cracking and moving out of place. Keep going. Don't freak, just go with it. Think of the way you look in human form. The way the bones are in place and how you move. Compare that with your wolf form. Note how the bone structure is and the muscles as it moves. Think of the bones moving inside of you. Get a mental Image of fur sprouting from every limb. Your skull squishing and teeth becoming sharper. Ears move further to the top of your head and become longer. Hands and feet, becoming paws. You have to think "I am the wolf! I am, I am!" Completely forget your even Human. You are a wolf in your mind. Then you are a wolf, In body.

Remember that Physically shifting your body can take as long as six months, to two years. It is a long, continuous practice that should be done once a day, at least an hour each.

But it can also can be reversed. To do this, Simply fall asleep, or set a timer to go off so that way you'll remember "Iv gotta go back!!". Trust me you DON'T want to be a permanent wolf. Also known as PNR. ​

Kiska's Method:

(Editor's Note: At the bottom of the method she says "way less painful" this is not true, as P-shifting is not "painful". Yes, It strains your muscles, but it is not a pain. Do not let is scare you)

To p-shift- lay down and close your eyes. Relax and only think of your animals form. the entire structure of him/her. Then you should start to feel numb. After you feel numb you need to start the shift somehow(pain).

So for the first shift i recommend partially shifting each body part . And i don't mean fully shift your leg and foot. i mean just somewhat shift each part. ok so it starts in your bottom right leg, bottom left leg, both thighs and tail , chest and back including your shoulders then head.SO before you start your head the rest of your body should look somewhat shifted. Then you fully shift your head and your body follows.

Now here's how i trigger the pain in the right leg- i start with the lower leg muscle and flex it kinda and it shoots up . then i just focus on my wolf. And for the chest you just stretch it to your head then your head automatically starts.

Now the entire time your gonna have to keep your eyes closed and think of your animals form

Things you'll need is- time, focus/concentration, high pain tolerance, and an isolated area such as your room at night time with the door locked.

how to endure the pain- for each part your shifting you need to put all you energy in that part before the pain starts. this will increase the endorphins in the part your shifting hence the less pain.

so after you move the pain around your body a few times you should be almost fully shifted. Then you think of a strong emotion and force your body to finish the shift. the first shift might take around 2 hrs . This method is the less pain full way but longest. ​ ​

Merfolk P-shifting methods

Pysical Shifting

A physical shift, is physically shifting into a mermaid. This method of shifting takes the most practice, but with a little effort you can do it. The hardest part about shifting is calling your mermaid form out. You can't have any doubt when doing this. Because if you do, the tail will not come out. 

The easiest way to accomplish P-shifting is to have the F-shift, and the M-shift down to a T. Meaning you have to know exactly what your shifting for. Having a clear image of your tail in your head always helps. Also, you may want to be wet when doing this, and be in a quiet space where nothing will bother you. Below I have listed many shifting methods you can use, all from different people, you can try each one out so you know which one works best for you. Physical shifting takes multiple tries, so don't get upset if it doesn't work the first time. 

Method 1 is about visualization. First, get comfy and relaxed from head to toe. Remember not to wear pants, considering it stops the shifting process, and they may rip. So if you aren't comfortable being naked, wear a big shirt. You can also use candles, and music that reminds you of mermaids. My personal favorite is "Beyond the Sea" by Celtic Woman. Next, close your eyes and start focusing on your energy from the top of your head, to the tips of your toes. See in your head your fluke forming to your desire. At this point you may feel some pain at your feet, toes, and ankles. Keep visualizing the pain as your mermaid self becomes physically tangable, physically real. Visualize your mermaid self coming out of your body, and becoming real.  Do this SLOWLY and do not rush. 

This quote is from KissingMidnight, who was one of the first online mermaids proven to be real. 
"...I focused on the sun going down, and I imagined the day time as me, the light part of me that’s mundane, and logical. And then I imagined the night as the ocean and mermaids, magick and things not seen or understood. As the sun was setting, I finally shifted into my true mermaid form. It felt weird at first, but at the same time it felt like stretching a sore muscle. So it was a little painful, but the good kind of pain...."

1.the legs join together and may or may not elongate. spine elongates into tail and feet become flukes. and any additional fins will form out of skin and tissue(s).
2. the skin tone begins to change(possibly. depends on person) and a smooth dolphin like skin covers the tail(from apendix down). then the scales, in the proper colours, begin to form on the areas you wish(from apendix down).
3. gills form(possibly. depends on person) and lungs become similar to a dolphins(so you can hold breath longer & possibly. depends on person).
4.webbed hands and any fins on arms form(possibly. depends on person).
5. all things that are on neck and head form and the mental parts of the mermaid really set in(instinct, behaivor, and all).

Other mermaid method

P-SHIFT:

Now this is how you would do your p-shift, what I (Brooke) recommend is that you let your mind tell you what to do, I think i'm so deep into shifting that all I can talk about is shifting, literally, my friend has gotten annoyed at me for not being normal for once. So off of my life, and onto yours! 

So for p-shifting I would either let your mind and body tell you what to do to try to bring out your mermaid side (if you're deep into the process), or practice the phantom-shifting technique, the one where you feel you have a tail, and all. This hasn't been on many lists of shifting as it is considered unimportant. The phantom shifting has only supposed to have been for you to meditate, but it's now helping me p-shift. 

The p-shift means physical-shift, basically doing what the name insists, physically shifting into a mermaid with a tail and gills and all! But if you don't know much about gills and expanded lungs I will tell you in the upcoming paragraphs! For now, some techniques for p-shifting. I will tell you the technique for ph-shifting, unless you already know this, then skip the first technique.

Technique No. 1: Phantom Shifting technique:

Sit in a comfortable position, legs right in front of you, together as if your legs were molded together, now lightly hold your legs together, not with your hands, rest your hands on your stomach, not by the sides of your legs. Now lie your back down once you know you are ready and breathe in through your nose, and out through your mouth. Keep on doing this, while FEELING as if your legs are slowly molding together, do NOT imagine in your mind your legs molding together, you have to feel it. Feel your legs getting closer and closer, until they mold together (even if it's not happening in real life, you still have to feel it, it may happen after multiple tries!) Feel as your feel are connecting and stretching out into a long, sturdy, fluke in the shape that you desire. Now unless you are in the bath do not shift gills. Feel your legs slowly, very slowly coming together and forming scales, then slowly turning the desired color. Once you feel the need or want to leave, then go. Unless this has worked so far and you got your legs to mold together you have to meditate and try to reverse this and get out of it. There, you're done!

Technique No. 2: Under Construction: 

Gills and Lungs:

Now that we've got most things covered, (unless you skipped a whole bunch of stuff, most things are very important) we are going to cover gills, and lungs. For those of you that are younger, or just do not know, you CANNOT have gills on land. If you tried shifting gills in your bedroom or living room, go to the bathroom immediately and wash some water on your neck/behind your ears/wherever you have your gills and run a bath immediately.  once you have get in it and let your gills breathe. See gills, if you got gills on land or in your house, not in a bathtub, you would die. See if you had gills, they are just an overpowering way of breathing, you would instinctively start breathing with your gills, as you would in the ocean, but if there was no water around to get oxygen from you would die.

Mermaid gills are in your nose, and behind your ears. Every mermaid has these gills, but if you really don't want these or you just want to perpetually hold your breath instead with expanded lungs be my guest. In addition to regular mermaid gills, you could also have and add on either gills, placed directly on the ribcage, or gills placed on the front sides of your neck. Remember that you need to know exactly everything about gills, how they work on the inside, etc. You need to know where your lungs are/where your air tube is and have those gills have areas to breathe from there.

Now we have lungs. if you would like you could have ONE large lung. But this may be harder for some, as you need to know where it would be, how the organs around you would work, etc. I personally would rather have gills, as I find them more easy shift into, but onto expanded lungs. For this you have to shift the insides of your body so you have one large lung, but you would need to come up for more air every once in a while because these are NOT gills and you cannot stay underwater forever with expanded lungs.
