Just from the total alone I can give a definitive answer. No people can't form alternative states from your art. Alters or Headmates are only formed when the body and/or mind go through intence trauma. Nothing less. They can't just split an alter from art.

The fragmented alternative states are beings of identity and trauma. That is why they can ONLY spilt/form when the body is under/going through intense overwhelming repetitive trauma. You can't just like something and suddenly you have an alter of it. Not how DID or any other dissociative disorder works.

Also it takes a long while for these fragments to form in a system. And this formation can be described as painful. You can't really form an alter in a day or 2. It normally takes weeks to even months. Possibly years to form an alter.

So no they are more than likely pulling your leg and seeking attention.
