Whereas earlier research had shown that Ss with lower auditory awakening thresholds (AATs) reported more dreams on awakenings from non-rapid eye movement (NREM) sleep, this study of 4 Ss over several nights each indicated no relationship between Stage 2 NREM dreaming and within-subject, within-night variations in AAT. Subjectively “deep” Stage 2 sleep was associated with high AATs and with...
Three S s slept with their eyes taped open and their pupils chemically dilated while stages of sleep were monitored by EEG and eye movement recordings. Various objects were illuminated in front of S s' open eyes. Shortly following the stimulus presentations, S s were awakened and reports of dream experiences and other imagery during sleep were obtained. Although there were occasional instances...
Twenty-four S s were exposed to controlled presleep stimuli. On one experimental night, they saw a violent episode, on the other, a nonviolent episode, from a TV western series. Dreams were collected using Dement and Kleitman's electrophysiological methods, by means of which rapid eye movement (REM) periods were used to identify “dream” periods. REM reports following the violent episode were...
