![]() “In addition, interactive dreaming could also be used to solve problems and promote creativity,” the researchers conclude. But this research indicates that people might really be able to study while asleep in a way that could help their waking life, like memorizing facts or visualizing high performance sports or music. ![]() The idea of learning during sleep has long become a sitcom cliché-someone listens to a dating tape or a stop-smoking tape, for example, and suddenly acts odd because of subliminal cues. “This work pushes us to think carefully-rethink, maybe-about some of those fundamental definitions about the nature of sleep itself, and what's possible in sleep.” One obstacle is that REM sleep must be “stabilized,” the scientists say, because even the eye movements themselves can wake people up sometimes.īenjamin Baird, a sleep researcher at the University of Wisconsin–Madison who wasn’t involved in this study, told Scientific Americanthe findings “challenge our ideas about what sleep is.” SciAm has more: Sleep has classically been defined as unresponsiveness to external environmental stimuli-and that feature is still typically part of the definition today, Baird explains. To make sure the subjects were really, truly in REM sleep, the scientists used the full capability of their polysomnography setup to measure “sleep physiology,” like a highfalutin’ version of waving your hand in front of someone’s face. But this is one of the first experiments to show that people having dreams can reach out from their dreaming state into real life. We’ve known for a while that dreams can include things prompted by real life, like a monster that turns out to be a stifling pillow or an alarm clock noise that joins the dream action. ➡ Join Pop Mech Pro and get exclusive answers to your burning science questions. The crazy part? Those dreamers are actually answering basic questions by moving their eyes back and forth.īy prompting people to lucid dream and asking questions, these scientists are proving dreams are permeable in both directions. Scientists at Northwestern University are doing a dream job-literally: they’re questioning people who are deep in dream-filled REM sleep. The sleepers remembered cues from waking life to do during sleep.Scientists used sleep study technology to measure and cue dreamers to do math.It turns out lucid dreamers can go one step further and answer questions while sleeping.
