Abstract:
Dreamers were long thought absolutely isolated from the outside world. Yet psychophysiological studies over the past 40 years have firmly established that lucid dreamers can use eye movements to report on their dream content in real time while in rapid eye movement (REM) sleep. We now also know that sensory input is not completely suppresssed during sleep. A recent study by Konkoly et al. illustrates how experimenters can question lucid dreamers during ongoing dreams and asks whether more extended two-way communication during lucid REM sleep dreaming is feasible.
