| Key findings | Dream recall frequency, mood, and content did not differ significantly between phasic and tonic REM awakenings, though phasic REM dreams were somewhat more colorful. Morning recall was predicted by dream meaninglessness, and to a lesser extent by good mood, colorfulness, dreams with words, and phasic REM sleep. |
Abstract
Eleven healthy subjects, 9 females and 2 males aged 21-23, were submitted to all night polygraphic recording and awaken in REM (Rapid Eye Movements) sleep, randomly upon tonic or phasic REM. Immediately upon awakening subjects were asked about possible dreaming according to the standardized questionnaire. Seventy-seven dreams, i.e. 79% of all 97 REM awakenings, were reported and analyzed. There were no significant differences in reported frequency of dreamings after awakening, mood and dream content due to phasic/tonic REM sleep. Dreams from phasic REM were a bit more colorful. Predictor of morning remembering of dreams was meaninglessness, not meaningfulness of dreams, and, in lesser extent, good mood, colorfulness, dreams with words and phasic REM sleep.
