Hypnosis can be achieved by virtually anyone who wishes to experience this state. In fact, people experience hypnotic like states many times in their everyday lives. From watching a funny movie, and laughing along with the plot, to driving around, when suddenly we find ourselves in the driveway wondering where the last 8 blocks have gone.
The individuals who cannot be hypnotized are those who are wither inebriated, have an IQ clinically below 70, or who simply do not want to be hypnotized.
