im really confused. sometimes i go into this psychosis induced state where im a character but theres no memories or anything its just like im suddenly her by personality and i dont know what to call that ??

I would call it a psychotic state, anon. It may be related to a dissociative disorder. I am not a mental health professional, and I can’t diagnose you. If these sudden personality changes confuse or distress you, I urge you to speak to a mental health professional about them.
