A great perturbation in nature, to receive at once the benefit of sleep and do the effects of watching. In this slumbery agitation, besides her walking and her other actual performances, what, at any time, have you heard her say? —W. Shakespeare

THE BEHAVIOR of somnambulists has led to a general belief that sleepwalking is the acting out of a dream.^1-3 In a previous study ⁴ we observed the relation of sleepwalking to the sleep-dream cycle directly, by utilizing the rapid eye movement (REM) method of dream detection ^* and obtaining electroencephalographic (EEG) recordings throughout the night by means of special cables or a biotelemetry unit which allowed for subject mobility. Nine subjects (seven male and two female) ages 9 to 23 years were studied for a total of 47 subject nights in our laboratory. Six of the subjects were children and three adults, age 16 years being . . . [Full Text PDF of this Article]

Dement and Kleitman6 have described four stages of EEG activity during sleep. Stage 1 is characterized by an absence of spindles and by a low-voltage fast EEG pattern. Stage 2 is typified by sleep spindles against a low-voltage background and Stages 3 and 4 by slow high-voltage activity (slow wave sleep). Associated with Stage 1 activity except when the subject is falling asleep are bursts of rapid eye movements (REM's). Stages 2, 3, and 4 are not associated with these eye movements and are called nonrapid eye movement periods (NREMP's).
