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 the 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 develop a more positive attitude. Hypnotherapy has also been particularly effective with stress disorders and various addictions.
