That’s what our brains can’t do in the background when we’re awake. There are certain questions that come up for which we plot a potential course of action or think through a future scenario to solve, Stickgold explains. triloks / Getty Images/iStockphoto The dreaming brain can build stories better than a brain that’s awake (And there’s a whole lot of evidence to support the idea that sleep makes learning and memory storing possible.)Īnd it might be that dreaming plays a role in that process, Stickgold says - “where the brain is trying to solve problems and complete processes that were going on during waking that it - in its waking hours - didn’t complete.” Even the really weird dreams may just be part of the brain’s process of elimination-approach to problem solving, experts say. Sleep for sleep-deprived people also tends to be more extreme neurologist Mark Mahowald of the University of Minnesota told Scientific American, “When someone is sleep deprived we see greater sleep intensity, meaning greater brain activity during sleep dreaming is definitely increased and likely more vivid.” Scientific American terms this effect “REM rebound,” and it can occur in a variety of situations.Our brains need offline time for processing and learning new things - and they do this during sleep. ![]() A 2005 study found that when subjects didn’t get enough REM sleep one night, their brains tried to make up for it the next, by engaging in longer periods of REM. Sleep Deprivation Can Cause Vivid Dreams.Ĭounterintuitively, not getting enough sleep can lead to more intense dreaming. If you awake unnaturally (through an alarm, for example), and the dream you just had feels unusually vivid to you, it may be because you were still in a REM stage when you woke up. People are best able to remember their dreams when awakened from REM (as opposed to naturally shifting to other parts of the sleep cycle). We first experience REM 70 to 90 minutes after falling asleep, and we go through a number of sleep cycles throughout the night, with REM cycles increasing in length as the night goes on. We may dream during other sleep stages, but those dreams will feel fragmented the types of dreams that have elaborate storylines and complex imagery are fueled by REM. REM sleep is responsible for vivid dreams. The study found that movements corresponded with new images appearing during sleeper’s dreams. A small 2015 study found that our eye movements actually mimic those of when we’re awake, only instead of responding to images out in the world, they’re responding to dreams. During REM, our heart rate increases, our breathing speeds up, and our eyes move back and forth beneath our lids. REM sleep is characterized by a high level of activity in the brain, as well as a temporary paralysis of the muscles. Sleep is divided into five different stages: Stages 1, 2, 3, 4 and REM. Although there is no definitive word on the purpose, mechanics, and nature of dreams, scientists have been able to make inroads into the study of our non-waking lives, theorizing why some dreams are different than others and why people experience dreams differently.Īre you having unusually realistic dreams? Here’s what science can tell you: It's All About REM Dreaming is only another part of this mysterious puzzle, and is even more elusive, as it’s even harder to study than sleep is. As sleep expert Ernest Hartmann points out in Scientific American, there’s a lot about sleep in general that we don’t know, including what sleep is for and why we experience REM (rapid eye movement). Why are some dreams more vivid than others? Why are some memorable, when others disappear instantly? The science of dreaming is not very well understood. I wake up feeling anxious, and the day hasn’t even begun yet. In my case, such dreams tend to be rooted in anxiety - visions of being chased, or of not being able to go where I want to go, or of having my teeth spontaneously fall out (Those are the WORST). However, once in a blue moon, I’ll have a very vivid, very real dream that leaves me confused and thrown. Most of the time, I don’t remember my dreams at all, and, although once in a while I’ll wake up knowing that I had a bad dream, or a good dream, or a sexy dream, the dreams themselves feel cloudy and tenuous. ![]() Is there anything more disorienting that waking up from a very vivid dream? Than that moment between sleeping and waking when you’re not sure if it was a dream, and you have to pause to untangle the dream events from real ones? I’m not someone who feels particularly in touch with my dream life. ![]()
