That's entirely up to you. You actually hypnotize yourself by following the directions of the hypnotherapist who is your guide. It's very simple and YOU have all the control.

Hypnosis is nothing to fear.
IF IF you have an I.Q. of at least 70. Hypnosis can't hurt you or make you do things you wouldn't ordinarily do. . . This same subject, on the same occasion, being truly super aware of what is going on at all times while in the hypnotic state, would never take off his or her clothes in front of everyone, or tell where he or she hides money, for instance, unless they would do so anyway while in a conscious state.
