A declassified CIA document dated 7 Jan 1953 [1] describes the creation of multiple personality in 19-year old girls. "These subjects have clearly demonstrated that they can pass from a fully awake state to a deep H [hypnotic] controlled state ... by telephone, by receiving written matter, or by the use of code, signal, or words and that control of those hypnotized can be passed from one individual to another without great difficulty. It has also been shown by experimentation with these girls that they can act as unwilling couriers for information purposes." BB 32
