Hypnosis is a mental state of consciousness involved with an enhanced capacity to respond to suggestion and a reduced peripheral awareness. It is used as a form of therapy to recall and integrate memories.
History[]
Samantha Carter had some experience with hypnosis in an undergrad psych course. (SG1: "Fire and Water")
When SG-1 had been mentally manipulated by an Ohne in 1997, Sam went under hypnosis with Dr. James MacKenzie to remember what happened on their mission on the planet Oannes. (SG1: "Fire and Water")
In 2005, Dr. Kate Heightmeyer performed hypnosis on Teyla Emmagan to help her telepathically connect to the Wraith. (SGA: "The Gift")
In 2006, a Wraith was taken captive and transformed into a human with the Iratus bug retrovirus by the Atlantis expedition and made to believe he was one of them with the name "Michael Kenmore". During this time, he asked Dr. Heightmeyer if his memory would ever return. She suggested trying hypnosis. (SGA: "Michael")
When Dr. Rodney McKay was host to a crystalline entity from M3X-387 in 2007, Lt. Colonel John Sheppard, Colonel Sam Carter and Teyla Emmagan discussed the possibility of giving the entity a chance to leave him. Carter suggested the possibility of McKay being hypnotized into a state where he could communicate with it. Teyla added that he had successfully meditated into an alternate state before. (SGA: "Doppelganger")
Camile Wray learned hypnosis from the International Oversight Advisory. She used it on Peter and Dr. Robert Caine so they could regain their memories of their time on Eden. (SGU: "Visitation")
