18 Myths About Hypnosis
When hypnotized repressed memories of trauma always emerge.
Hypnosis can be used to uncover repressed memories, but the hypnotic state itself does not, by default, bring them to the surface. A client will never see something that he or she is not ready to see and such memories will only come up if the client and/or the hypnotist intend to bring them up.
