In this New York study, the subject, a female caucasian in her mid 20’s, was subjected to hypnosis prior to dental work. Later she became suicidal but was amnesic of these events as she entered the fugue state triggered by this stress. Diagnosed with undifferentiated schizophrenia with fugue states, this resulted in the unconscious mind becoming the dominant part for a time, amnesic of all events – consistent with the Dissociation Theory of hypnosis. She was treated and recovered well.
