The fact is, a hypnotic trance is a natural state most of us visit on a daily basis. For example, most of us have driven a distance while thinking of other things, when suddenly we realize that we don't remember having passed certain exits or streets. That is called 'waking hypnosis'. Since the conscious part of the mind was not focused on driving, the subconscious mind (the part programmed through repetition) took over and got there safely. Or, a very light hypnotic trance could occur when a person is so engrossed in a novel or movie that he or she is there and real surroundings don't seem to exist.
