Ss who typically fail to remember dreams at home (nonreporters) and Ss who frequently remember dreams (reporters) slept in the laboratory for 4 nights each. Gradual or abrupt awakenings were made at each EEG Stage-1 REM (dream) period. Although nonreporters and reporters did not differ in REM-period frequency or EEG patterns during sleep, nonreporters did report dreaming less frequently...
Thirteen subjects were studied for 4 nights of sleep by simultaneous recording of EEG, eye-movement potentials, heart rate, and respiration. The subjects were awakened from stage 1 sleep periods with rapid, conjugate eye movements (REM periods) and asked to describe any preawakening experiences (dream or thoughts). Respiratory rate was more irregular during REM periods which led to dream...
Eleven subjects were awakened from dream periods (defined in terms of Dement and Kleitman's eye-movement criteria) and asked to describe their dream experience. Subjects more often believed that they were awake and/or thinking when the awakening was gradual than when the awakening was abrupt (P <.05). Reports in which the subject believed that he had been awakened from a dreamless sleep were...
