Dreams can happen at any time during sleep. But you have your most vivid dreams during a phase called REM (rapid eye movement) sleep, when your brain is most active. Some experts say we dream at least four to six times a night.
4. You can have several—even a dozen—dreams in one night. It's not just one dream per night, but rather dozens of them, say experts—you just may not remember them all. "We dream every 90 minutes throughout the night, with each cycle of dreaming being longer than the previous," explains Loewenberg.
The average person has three to five dreams per night, and some may have up to seven; however, most dreams are immediately or quickly forgotten. Dreams tend to last longer as the night progresses. During a full eight-hour night sleep, most dreams occur in the typical two hours of REM.
Experiencing recurring dreams may point at underlying issues regardless of the dream's content. Adults who experience frequent recurring dreams tend to have worse psychological health than those who do not, and many experts theorize that these dreams may be a way to work through unmet needs or process trauma.
Dreaming sleep is characterized by rapid eye movements known as REM. The longest recorded period of REM is one of 3 hrs 8 mins by David Powell (USA) at the Puget Sound Sleep Disorder Center, Seattle, Washington, USA on 29 April 1994.
Each hour in the real world would take two years and four months in the dream state.
Other weird records
Previously, Peter Tripp held the first record at 201 hours and suffered from hallucinations for several days after. Between Peter and Randy, Honolulu DJ Tom Rounds made it to 260 hours. Randy tapped out at 264 hours, and slept for 14 hours straight after.
Dreams can be so realistic that it can be hard to tell if we're awake or asleep. And sometimes, we wake up in the middle of a dream and wonder if it's possible to go back to sleep and pick up where we left off. It is possible to resume a dream, but it requires a certain focus and concentration.
“That dreaming may represent important cognitive functioning. Brain activity that occurs when we're dreaming is similar to the memory processing brain activity we experience when we're awake.” When you're experiencing more stress or anxiety, you tend to dream more, too.
During non-REM sleep, the thalamus is inactive, but during REM sleep, when we are dreaming, the thalamus is active, sending the cerebral cortex images, sounds, and sensations, which is why we are able to hear, feel, and see in our dreams similarly to how we do when we are awake.
When awakened while dreaming, people rend to report that their dreams contained vivid colors seventy percent of the time and vague color 13 percent of the time, but outside of scientific studies, only 25 to 29 percent of people say that they dream in color. So many of us do dream in color but don't properly remember.
Recurring dreams often occur during times of stress, or over long periods of time, sometimes several years or even a lifetime. Not only do these dreams have the same themes, they can also repeat the same narrative night after night.
“Since dreams are thought to primarily occur during REM sleep, the sleep stage when the MCH cells turn on, activation of these cells may prevent the content of a dream from being stored in the hippocampus – consequently, the dream is quickly forgotten.”
Everyone dreams anywhere from 3 to 6 times each night. Dreaming is normal and a healthy part of sleeping. Dreams are a series of images, stories, emotions and feelings that occur throughout the stages of sleep. The dreams that you remember happen during the REM cycle of sleep.
But experts can provide estimates about how long you may spend dreaming. According to the National Sleep Foundation, the average person dreams four to six times per night. You might spend as much as 2 hours in dreamland over the course of a night's sleep, reports the National Institutes of Health.
So basically, it is possible to dream without getting a good quantity of quality sleep. But, if you're having those vivid REM dreams, then that's usually a sign you're getting good sleep, according to Dr. Dasgupta.
Dreaming is a normal part of healthy sleep. Good sleep has been connected to better cognitive function and emotional health, and studies have also linked dreams to effective thinking, memory, and emotional processing.
Dreaming enhances creativity and problem-solving. It's been shown that deep non-REM sleep strengthens individual memories. But REM sleep is when those memories can be fused and blended together in abstract and highly novel ways.
Possibly. People are more likely to dream about the things they worry about the most during their waking hours, so the best way to induce a targeted dream is to truly believe that it's important. That's no help to sleep researchers, who often need their subjects to dream about trifles like a maze or brain teaser.
We can't know for certain if a person never dreams. We do know that some people rarely, if ever, recall their dreams. If you have trouble remembering dreams, you're in good company. Most of us have 4 to 6 dreams a night, but we forget the vast majority of them.
Dreams can get pretty weird sometimes. When you wake up from one that was particularly bizarre or vivid, you might feel relieved it was only a dream, one you'll never have to experience again. Well, that last part might not always be the case. Some dreams come back not just once, but again and again.

Al Herpin, who lived in Trenton, New Jersey, claimed to have never slept. The supposed cause is unknown. While claims such as his have occasionally appeared in newspapers, there is a recognized medical consensus that all humans require sleep, and that they do so even if they are not aware of it.
