Anyone can be hypnotized if they want to. No one can be hypnotized against your will. It is a normal state that everyone goes through before falling asleep, where your brain waves change from Beta to Alpha. However, it is possible to resist hypnosis just as it is possible to resist sleep. But even if someone resists hypnosis, there are techniques that can be used to overcome the resistance. Of course, if someone has no desire to be hypnotized, then they simply will not succumb, but this is a rare situation because most people want to experience the benefits associated with hypnosis.
