Earlier I mentioned about the two theories of hypnosis – State Theory and Expectancy Theory.
The State Theory says that hypnosis is whereby a person enters into a state called trance through relaxation or other induced methods.
Expectancy Theory says that hypnosis is whereby a person, out of his expectation, enters into a hypnosis (if he expects to behave well in public so that he projects a good image, then he will co-operate with the hypnotist). He induces himself.
In other words, State Theory says other people induce you into hypnosis. Expectancy Theory says you induce yourself into hypnosis. And there is a third theory which I shall name it Nature Theory. Nature Theory says you can be induced into hypnosis not by yourself or other person but by things around you.
