in a panic, she managed to knock out the crocodile and free herself. salem, a new mother, had been breast-feeding her daughter for five months before the croc-attack dream, living on four hours of sleep a night. miss a few from lack of sleep and the brain keeps score, forcing payback soon after eyelids close. in this state we dream the most and our brain activity eerily resembles that of waking life. sleep is divided into rem and four stages of non-rem; each has a distinct brain wave frequency. as the night progresses, however, non-rem stages shorten and the rem periods grow, giving us a 40-minute dreamscape just before waking. of course there is non-rem rebound as well, but the brain gives priority to the slow-wave sleep and then to rem, suggesting that the states are independent of each other.
of course, rem deprivation, and the subsequent rebound, is common outside the lab. when patients stop the meds, and the vices, they’re rewarded with a scary rebound. psychiatrist jerry siegel, head of the center for sleep research at the university of california, los angeles, recently proved that rem is nonexistent in some big-brained mammals, such as dolphins and whales. “dying from lack of rem is totally bogus,” siegel says. fetuses and babies spend 75 percent of their sleeping time in rem. john antrobus, a retired professor of psychology and sleep research at the city college of new york says that dream content is tied to our anxieties. for that we have to ask what is the purpose of thought.
you were tossing and turning all night, and you remember the dream you had so vividly, as if it really happened. or does it mean you went on an excellent adventure at the expense of your beauty rest? as with most things in the sleep world, though, it’s just a little bit complicated. the first two stages involve light sleep and slow brain waves (like the kind of sleep you get during a quick catnap), and the third stage is when you’re the most “out of it” — aka when it’s the hardest to be woken up from your slumber. in rem sleep, per the aasm’s breakdown, your breathing picks up, your eyes flutter beneath your eyelids, your body moves into a deep sleep, and it’s also when your brain activity is heightened enough for you to experience vivid dreams.
but even though rem sleep typically means 1) that you’re in a deep sleep, and 2) that you’re likely dreaming, dr. dasgupta says it’s possible to dream a lot throughout the night and not get a good night’s sleep. in other words, sometimes you dream during one of those earlier, lighter stages of your sleep cycle, but when that happens, you usually forget a lot of the details of the dream because you weren’t really that deep in your slumber. if you’re getting a good quantity of sleep, but still having symptoms of not a good rest, then that means you’re not going into the deep stages of sleep. what’s more, when you’re getting a good night’s sleep and experiencing rem dreams, it can actually improve your ability to do certain things when you’re awake. similarly, a study published in the scientific journal current biology found that, if you learn a new task and then sleep on it, you could be up to 10 times better at that task compared to someone who stayed awake. so, dreaming might not always mean you’re getting a quality night of sleep.
dreams do not typically negatively impact sleep, but nightmares can. the way they influence sleep is that it can make it more difficult to fall asleep and cause “when someone is sleep deprived we see greater sleep intensity, meaning greater brain activity during sleep; dreaming is definitely increased sleeping issues that cause a lack of sleep, such as insomnia and narcolepsy, can increase one’s risk of experiencing vivid dreams. changes, vivid dreams every night tired, vivid dreams every night tired, which sleep is better with dream or without dreams, vivid dreams nhs, how to dream less and sleep better.
