All these process involve physical relaxation and a narrowing of consciousness. In the case of hypnosis, its it task or goal oriented, as we are mentally working on something such as weightlessness. Many mediators use hypnosis and can slip from one state to another quite easily. The hypnotist can make you do things against you will. The hypnotist has no powers over you at all, and cannot make you do things against your will.
All hypnosis is self myth's.
The hypnotist merely guides you into a hypnotic state, and feeds your mind with carefully worded suggestions. If you felt uncomfortable with these suggestions, you may reject them at will. Hypnosis is essentially a matter of cooperation between the hypnotist and his subject, not some form of power the hypnotist possesses which will compel the subject to submit to his or her will. If you are under hypnosis and the hypnotist suddenly left the room, two things may happen. You will either realize that the hypnotist is no longer talking to you, and will open your eyes, feeling fresh and alert.
