Lina doesn’t need to be hypnotized. One evening she writes an assignment for school, and the next day she finds the text all ready on her desk, without remembering to have written it. She did it under a different personality.
The phenomenon of psychic dissociation began with hypnosis and hysteria one hundred and fifty years ago; today it has taken on a new form with dissociative identity disorder, which can bring together dozens, even hundreds of personalities in the same individual.
