Hypnosis is a state of consciousness involving focused attention and reduced peripheral awareness characterized by an enhanced capacity for response to suggestion. There are two broad groups of theories as to what is occurring during hypnosis. ''Altered state'' theories see hypnosis as an altered state of mind or trance, marked by a level of awareness different from the ordinary conscious state. In contrast, ''Non-state'' theories see hypnosis as a form of imaginative role-enactment.
