Formshifter

undefined:

A formshifter, or sonashifter; is an individual, headmate, system, or sisasystem; who shifts between different "forms" or "sonas" in a way that's very similar to switching between headmates, without these forms being separate beings.

A formshifter is a singular person or singular collective who shifts between their forms. A formshifter system or sisasystem would experience formshifting in a monoconscious, collective way. Forms are usually not separate headmates, although it is possible for them to become one, temporarily or permanently; as well as a headmate to turn into a form. The way formshifting works can fluctuate, and there are in infinite amount of ways one may experience this phenomenon.

Each form may have different personalities, identities, neurodivergence symptoms, may hold specific traumas, so on and so forth. A form can be pretty much anything a headmate can be, just without being a separate being. There is no limit on how similar or how different the forms could be from one another.

Someone may refer to their "forms" or "sonas" with different wording as well if they prefer, they do not have to use these words to describe their forms.

Formshifters may choose to consider their experience to be within the median-multiple spectrum, or not. Generally it is a median-like experience, but people do not have to associate their experience with the term. This term's purpose is not to explain how separate one's headmates or consciousness may be, it is more about how one being or collective's overall personality, identity, and so on can shift into different states without these states being separate beings.
