The author, Barkworth, compares actions done by people in hypnotic states. He distinguishes between mental or physical actions and voluntary, automatic or intuitive actions. Barkworth reviews several of these types of cases, occurring with or without hypnotism. A few of these cases also involve automatic writing. One case in particular involves a patient’s ability to learn music and perform it at a later time with or without the written music notes.
Dr. Myers reviews multiple cases involving altered personalities. These personalities have been brought on by a variety of means, including dreams, drug use, physical disturbance, epilepsy or hypnotism. Some of the cases involve automatic writing. Dr. Myers discusses each of these cases briefly with an emphasis on the differences between the conscious and unconscious self.
