Note then, that this kind of everyday trance is different from the trance brought about by deep hypnosis, and is comparable to that relaxed mental state between wakefulness and sleep. There is also a difference between auto-hypnosis, where the state of extreme suggestibility is self-induced; and hetero-hypnosis, where it is induced by a hypnotist or another person. All these we will try to explain further in the succeeding chapters.
In all of the above mentioned categories, the hypnotized person, as stated in the Encyclopedia Britannica, seems to respond in an uncritical, automatic fashion, ignoring aspects of the environment (e.g., sights, sounds) not pointed out by the hypnotist. Even the subject's memory and awareness of self may be altered by suggestions, and the effects of the suggestions may be extended (post-hypnotically) into the subject's subsequent waking activity
In self-induced hypnotism, a person feels relaxed and very open. As in while buried in a book or engrossed in a film, concerns about the real world seems forgotten for a while and temporarily escaped from.
This is parallel to hypnosis with the aid of a hypnotist. If the hypnotist states the person under his spell is in extreme heat, the person may start to sweat and experience high temperature, even if it the atmosphere is perfectly fine. If he suggests to a timid and painfully shy person that he is in fact an extremely confident man who is so sure of himself, the person may suddenly feel open to socializing with other people, strangers even.
