Three cases of sleep paralysis—defined as a state in which consciousness is awake while motor functions are asleep—in returned Air Force personnel suffering from combat fatigue are reported. The condition occurred singly, not in association with cataplexy, narcolepsy or somnambulism. Analysis led to the impression that sleep paralysis is, in all probability, related to a state of confusion as to emotion and intention, with resulting indecision. With undue modesty the authors call their analysis and therapy 'superficial'. Actually, their description and analysis is a valuable contribution to the understanding of this psychogenic sleep disturbance.
