Most people assume dreaming is something exclusive to sleep; however, a new study from the Paris Brain Institute suggests otherwise.
The study found that the strange, shifting mental experiences we usually associate with dreaming can also occur while we are awake. These episodes leave a measurable trace in the brain. The results, published in Cell Reports, challenge the common idea that dreaming and waking thought are completely separate experiences.
“Being awake is not synonymous with being attentive, fully aware of one’s surroundings, or able to act and think rationally,” said Delphine Oudiette, co-leader of the institute’s DreamTeam and senior author of the study. “We now know that there is a continuum between wakefulness and sleep, with intermediate states such as mind-wandering or mind-blanking, during which certain regions of the brain may be asleep.”
To investigate how the brain transitions from wakefulness to sleep, the researchers worked with 92 people who often take naps and could describe their thoughts when prompted. The experiment was based on a method used by Thomas Edison, who would fall asleep while holding a heavy object. When he drifted off, the object would fall and wake him up, allowing him to recall what he was thinking at the edge of sleep.
