In a July 2001 article for Scientific American titled "The Truth and the Hype of Hypnosis", Michael Nash wrote that, "using hypnosis, scientists have temporarily created hallucinations, compulsions, certain types of memory loss, false memories, and delusions in the laboratory so that these phenomena can be studied in a controlled environment."
There are a number of articles, books, and audio guides available for free or purchase online that can give you pointers or guides for self hypnosis. There are also hundreds of self hypnosis apps available for download. However, it is important to note that many of these apps have not been scientifically tested, and are not proven to work, but if they help relax you, there’s little downside.
Some therapists use hypnosis to recover possibly repressed memories they believe are linked to the person's mental disorder. However, the quality and reliability of information recalled by the patient under hypnosis is not always reliable. Additionally, hypnosis can pose a risk of creating false memories -- usually as a result of unintended suggestions or the asking of leading questions by the therapist. For these reasons, hypnosis is no longer considered a common or mainstream part of most forms of psychotherapy. Also, the use of hypnosis for certain mental disorders in which patients may be highly susceptible to suggestion, such as dissociative disorders, remains especially controversial.

Hypnotherapy is guided hypnosis, or a trance-like state of focus and concentration achieved with the help of a clinical hypnotherapist. This trance-like state is similar to being completely absorbed in a book, movie, music, or even one's own thoughts or meditations. In this state, clients can turn their attention completely inward to find and utilize the natural resources deep within themselves that can help them make changes or regain control in certain areas of their life.
