When under a "hypnotic trance" you won't do anything that you wouldn't normally do. For instance, if I were to put someone into a "hypnotic trance" and then told them to kill someone, they wouldn't do that, unless they were already willing to kill. All that really happens is that the hypnotist suggests things and the participants go along with it.
However, hypnotism isn't something people should play around with. There are many things that can go wrong. Since the people are willing, you can really mess with their minds. You can actually implant memories, so that when they do "wake up", they will believe that the memories that you implanted are true. So it's not something that should be played with. You have to be responsible.
I agree i think you can hypnotise people but you cant make them do something they dont want to do.But it is dangerouse so be careful.
