Naiman describes the brain during REM sleep as a sort of “second gut” that digests all of the information gathered that day.

Scientists are divided as to whether dreams are simply a product of random neurons firing during sleep, or if they’re something more - like a data dump that helps the brain separate important memories from non-important ones, or a way for people to prepare for challenges and play through different scenarios in their heads. (The dreams you remember when you wake up are only part of REM sleep, says Walker in reality, the brain is highly active throughout the entire phase.) But there is also decreased activity in other regions, like the one involved in rational thought - hence the reason for extremely lucid, but often nonsensical, dreams.

And because longer periods of REM sleep only happen during the final hours of sleep (in the early morning, for most people), it can get cut off when you don’t spend a full seven or eight hours in bed, says psychologist Rubin Naiman, a sleep and dream specialist at the University of Arizona Center for Integrative Medicine and the author of a recent review about dreaming published in the Annals of the New York Academy of Sciences.ĭuring REM sleep, there is more activity in the visual, motor, emotional and autobiographical memory regions of the brain, says Matthew Walker, professor of psychology at the University of California, Berkeley and author of the new book Why We Sleep. REM sleep stages tend to be relatively short during the first two-thirds of the night as the body prioritizes deeper, slow-wave sleep.
