I understand why some people think that. Stage hypnosis for entertainment looks like the hypnotist can make anyone do anything
People imagine they go into trance, have little control and drool and act like a zombie
The truth is.. trance is a naturally occurring state that we go in and out of in our every day lives. Typically times are driving, driving in time becomes an automatic behaviour (meaning it is impressed into our unconscious mind) and we don't think about. This trance like state.
It also happens when we are engrossed in a movie or good book. Something we are emotionally engaged in or even when we are bored and day dreaming.
