Hypnosis is an altered or changed state of awareness, concentration, or perception. Hypnosis can be used to remember previously unrecalled events, reduce anxiety, cope with pain, stop smoking, increase self motivation and other uses. A popular misconception is that one is not in control when under hypnosis. In the manner that it is used in therapy, the client is always in control of the situation. Hypnosis may be self induced to achieve a relaxed state.
