Under hypnosis you will only do what you feel comfortable doing, you are in complete control.

When you see stage hypnotists they have people do all sorts of things; the only reason they are doing them is because the person's subconcsious sees nothing wrong and chooses to do it. If you ever attend a stage hypnotist show, they do a lot of tests with the audience and then they pick the most susceptible to being hypnotixed and want to have fun. Stage hynotists know that if they pick someone who is a stick in the mud or doesn't really want to do these things then they won't. If a hypnotist asks one to do anything that conflicts with their own personal subconscious, the suggestion will not be carried out. Thus, when one agrees to volunteer themselves in a show like this; he/she has already given their mental conscent and thus their subconscious will follow.

Your mind will also not respond to any suggesstion that may be harmful to you or another person, it is built into our system.
