Hypnotherapy uses hypnosis as a psychotherapeutic tool. The altered state that occurs under hypnosis has been compared to a state of deep meditation or transcendence, in which innate recuperative abilities of the psyche are allowed to flow more freely. The subject can achieve greater clarity regarding personal wants and needs, explore other events or periods of life requiring resolution, or generally developing a more positive attitude. Hypnotherapy had also been particularly effective with stress disorders and various addictions.
