"Human beings are under the control of a strange force that bends them in absurd ways, forcing them to play a role in a bizarre game of deception."-Dr. Jacques Vallee, Messengers of Deception, p. 20
"We are dealing with a multidimensional paraphysical phenomenon which is largely indigenous to planet earth."-Brad Steiger, [cited in] Blue Book Files Released in Canadian UFO Report, Vol. 4, No. 4, 1977, p. 20
"A large part of the available UFO literature is closely linked with mysticism and the metaphysical. It deals with subjects like mental telepathy, automatic writing and invisible entities as well as phenomena like poltergeist [ghost] manifestation and 'possession.' Many of the UFO reports now being published in the popular press recount alleged incidents that are strikingly similar to demonic possession and psychic phenomena."-Lynn E.
