Why some people remember and others forget This region can also put you in a state of intra-sleep wakefulness, which, in turn, allows your brain to encode and remember dreams better,” Julie Lambert, certified sleep expert, explains.Ī study published in the journal Neuropsychopharmacology and reported by International Business Times suggested that those people who reported high dream recall had more activity in the temporoparietal junction than those who didn’t recall their dreams often. “There’s a region in your brain called the temporoparietal junction, which processes information and emotions. On the flip side, brain activity can also allow someone to more easily remember their dream. Thus it is normal to forget dreams, most of the time.” Dimitriu says.Įver had one of those dreams that are so realistic you aren’t sure if the events really happened? It’s really unsettling and strange, right? So in this case, our brain may help us forget so that we’re better able to tell the difference between our dream world and the real world. “The dream activity can be so real and intense that our brains actually hide, or mask away the dream, so get lost between our waking experience, and our dream lives. So people who recall dreams may have a difference in their ability to memorize things in general.īeyond that, a person’s brain may actually block out a dream so we don’t remember it the following day. “And, if our need to dream is any indication of the brain participating in a restorative process, our inability to remember our dreams may simply be due to the sorting of essential and nonessential information during sleep.”īasically, this theory suggests that dreams occur when our brain is processing information, eliminating the unnecessary stuff and moving important short-term memories into our long-term memory. Sujay Kansagra, Mattress Firm’s sleep health expert, tells Healthline. “While some may suggest that dreams are a window to the subconscious, other theories posit that dreams are a nonsense result of the activity that takes place while we sleep and restore our brains,” Dr. This is partly because the brain activity can’t tell us about the content of dreams, and you have to rely on subjective accounts from people. Dream research is a wide and complex field, and dreaming can be hard to study in a laboratory. That answer can vary depending on which theory of why humans dream you decide to follow, because there’s quite a few. So if everyone dreams, why don’t we all remember them? Alex Dimitriu, double board-certified in psychiatry and sleep medicine and founder of Menlo Park Psychiatry & Sleep Medicine, tells Healthline. It is an essential function for the human brain, and also present in most species,” Dr. “Whether they remember or not, all people do dream in their sleep. This stage usually begins about 90 minutes after you fall asleep, and can last for up to an hour toward the end of sleep. Mike Kisch, co-founder and CEO of Beddr, a sleep tech start-up, tells Healthline that dreaming tends to occur during this time because our brain wave activity becomes more akin to that of when we’re awake. This sleep stage is characterized by rapid eye movement (what REM stands for), increased bodily movement, and faster breathing. Dreaming tends to take place during REM sleep, which can occur multiple times a night. Let’s start with why and when dreaming occurs.
