Hypnosis is a state of human consciousness involving focused attention and reduced peripheral awareness and an enhanced capacity for response to suggestion. The term may also refer to an art, skill, or act of inducing hypnosis. Theories explaining what occurs during hypnosis fall into two groups. 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, nonstate theories see hypnosis as a form of imaginative role-enactment.
