Hypnosis can be considered a state of heightened suggestibility where the hypnotist communicates directly with the subconscious of a subject without the interference from the conscious mind.
Self-hypnosis involves the same principles but without the guidance of another person. As such, an individual can put him- or herself into a state of hypnosis with the aid of different techniques. As
with “hetero-hypnosis”, or hypnosis induced by a hypnotist, the subject only enters into the hypnotic state when s/he is ready to do so and then controls the response to suggestions.
As a form of hypnosis, that is self-induced, self-hypnosis makes use of self-suggestion and requires motivation to change and a carefully crafted script that is based on a well-defined goal. It also makes use of progressive imagery to induce a deep hypnotic state to subdue the conscious mind and allow direct access to the subconscious. Importantly, accept that self-hypnosis does not work for everybody, at least not initially. Prepare properly, be willing to focus your attention and be patient.
