This surprisingly simple theory was proposed by Y.D. Tsai in 1995 as part of his psychosomatic theory of dreams. Inside each brain, there is a program " I " (the conscious self) which is distributed over the conscious brain and coordinates mental functions (cortices), such as thinking, imagining, sensing, moving, reasoning … etc. "I" also supervises memory. Many bizarre states of consciousness are actually the results of dissociation of certain mental functions from "I". When a person is hypnotized, it might be that his/her imagination is dissociated and sends the imagined content back to the sensory cortex, resulting in dreams or hallucinations; or that some senses are dissociated, resulting in hypnotic anesthesia; or that motor function is dissociated, resulting in immobility; or that reason is dissociated and he/she obeys the hypnotist's orders; or that thought is dissociated and not controlled by reason, hence strives to straighten out his/her body between two chairs. A command can also be acted out long after the hypnosis session, as follows: The subject obeys the voice of reason in normal state, but when hypnotized, reason is replaced by the hypnotist's command to make decisions or believes, and will be very uneasy if he/she does not do things as decided or his/her belief is contradicted. Hypnotherapy is also based on this principle.
