User:Goose121/sandbox/Multiplicity (psychology)

Multiplicity is the psychological phenomenon in which a body can display multiple distinct personas. This phenomenon can feature in identity disturbance, dissociative identity disorder, and other specified dissociative disorders, among other things. Some individuals describe their experience of multiplicity as a form of neurodiversity, rather than something that demands a diagnosis. Since 1994, the Diagnostic and Statistical Manual of Mental Disorders (DSM) no longer refers to it as "multiple personality disorder", favoring other terms.

History
Throughout history, concepts of phantoms, muses, and fluid "selves" have been applied to this phenomenon. This has been extended to concepts such as tulpamancy. Additionally, some individuals throughout history have stated that they had been taken over by a spirit, soul, or ghost.
