I looked into hypnosis to resurface supressed memories. I checked medical studies and , if I understood them correctly, science regarded hypnosis to resurface supressed memories as a myth that had no scientific basis. Even worse, you risked creating new memories that didnt exist to begin with.
But it was a long time ago and I have no medical background. Maybe I didnt understand what I was reading and hypnosis really can be of help in those cases.
