The hypnotist can make you do things against your will?

This is a false statement. The hypnotist has no powers over you at all, and cannot make you do things against your will. All Hypnosis is really self-directed and self-controlled. The hypnotist merely guides you into a hypnotic state, and feeds your mind with carefully worded suggestions. If you feel uncomfortable with these suggestions, you may reject them at will.

What is hypnosis?

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.
