DID

Dissociative Identity Disorder is the abnormality which people commonly confuse with schizophrenia. Having multiple different personalities is something which must be very hard to deal with, especially without any control over which personality takes over at certain times and places. In the movie"Psycho" it involves identity disorder in a major way. The main character takes on his mother's personality after her death, and commits brutal murders without being able to remember what happens. Cases as serious as that one have happened, and they put the real struggles of disorders like these out in the open. This disorder is also highly contested, and very little factual evidence has been obtained via research. Much is still unknown about this potentially life destroying mental illness.
