Not at all! I can not make you do anything you do not want to. Your mind will not allow you to do anything that is against your values or ethics, or disclose anything that you do not want to talk about. Clinical hypnotherapists use hypnosis only for therapeutic purposes, to help their clients achieve their goals.
Stage hypnotherapists are entertainers and select their participants carefully choosing volunteers that want to be on stage and are comfortable being silly for the entertainment of others.
