It may occur spontaneously or be suggested, and may be suggested, and may be partial or total.

In chemically induced anesthesia there are two types: general, which produces unconsciousness; and local, which causes a specific area of the body to be insensitive to pain. In the context of hypnosis this is called hypnoanesthesia, and is used in major surgical and dental procedures.

Done skillfully, it helps create rapport.
Negative Hallucination: A hallucination in which the subject fails to perceive something that is present.

Operator: Synonymous with hypnotist or hypnotist.
Permissive: This approach to hypnotic induction is the opposite of authoritarian. A permissive suggestion is made in such a manner as to give the subject the option of responding. The subject, not the hypnotist, is made the perceived source of the response. Permissive suggestions never have an intonation of authority or command.
Positive Hallucination: A perception of a stimulus that does not exist in objective reality.
Posthypnotic Response: Acts carried out after the termination of hypnosis in response to specific suggestions are called posthypnotic. A suggestion given during hypnosis serves as the stimulus and the act becomes the response.
Posthypnotic Suggestion: A suggestion given during hypnosis that occurs in the subsequent waking state.
Revivification: A reliving of a prior period of life. In revivification the hypnotized person returns to a physiological state believed to have existed at the time to which the subject has returned. All memories following the age to which the subject has been regressed are removed.
