Hallucination - A hallucination can be described as an experience of one or more senses which occurs without an external stimulation. In other words the cause of the sensory activation is internal and is common in psychosis and drug misuse. The phenomenon can be evoked in the deeper states of hypnosis and also with direct electrical stimulation of the brain. Positive hallucination describes the process of experiencing something that is not actually present. Negative hallucination describes the process of not experiencing something that is present.
Hand Clasp Test -This test of susceptibility is common in stage hypnosis but little used in therapy. Quite simply the subject is asked to clasp his hands together by interlocking the fingers. The hypnotist might then make suggestions that the hands are sticking together, tighter and tighter. Eventually the subject is told flatly that his hands are locked together and he will not be able to separate them until the hypnotist gives that instruction. If the subject is unable to part his hands, or has some difficulty in this act, he is judged to be susceptible to hypnotic suggestion at that time.
