In 1985, Stephen LaBerge performed a pilot study which showed that time perception while counting during a lucid dream is about the same as during waking life. Lucid dreamers counted out ten seconds while dreaming, signaling the start and the end of the count with a pre-arranged eye signal measured with electrooculogram recording.[31]
Would this be refuted by cases where lucid dreamers were able to communicate (one way) with researchers during their dreams through eye movements?
