Time assessment during sleep when attempting self-awakening was compared with natural awakening. Volunteers (n = 10) went to bed at normal bedtime in a sleep laboratory. On certain nights they were designated to awaken by themselves after sleeping 80% of their average sleep-time (self-awakening), and on other nights to sleep until they awoke naturally (natural-awakening). Five minutes following REM sleep onset, they were forcedly awakened by the experimenter and were asked the time of day (time assessment) and subjective ratings of sleep depth, sleepiness and mood. The results indicated that subjective ratings were not significantly different between the two conditions, but time assessment was : participants assessed time more accurately on self-awakening nights compared to natural-awakening nights. These results suggest that when attempting self-awakening, people can awaken from sleep at the correct time because they accurately assess time during sleep.
