2, dual personality, multiple personalities
Multiple personalities, and dual personalities, all belong to split personality (these three belong to the same category), which is called dissociative disorder in psychiatry. If each personality is a different role, then these different “roles” each have their behavioral habits, ways of thinking, their living environment, and their perceptions, and they take turns dominating a person’s behavior. Several souls live in the body.”
The main feature is the identification disorder of self-identity, so this multiple personalities will be called hysterical identification disorder, identity conversion (dissociative) disorder.

The two personalities in a dual personality do not share memories, nor can they exist (active) at the same time.
