Lucid dreaming—dreaming while aware that one is dreaming—was verified in five selected subjects who signaled that they knew they were dreaming while continuing to dream during unambiguous REM sleep. The signals were specific dream actions with observable physical counterparts, performed according to pre-sleep agreement. This signaling ability allows proficient lucid dreamers to conduct dream experiments, marking the exact timing of dream events to enable precise psychophysiological correlations and systematic hypothesis testing.
