From a scientific point of view, why do some people sleep and rarely dream?

Dreams are a natural choice for creativity. In other words, the human brain is constantly thinking, there are all kinds of egg pain and ideas that may be quite reliable even if they seem to be egg pain, and dreams are the testing ground, the jungle of natural selection, and only the best ideas can stand out.

Based on long-term experience and scientific testing, it has always been known that "sleep helps memory". Experiments by Robert Stickgold and his team in 2010 found that dreaming during napping boosted a person's memory by a factor of 10. Or is it because of this mysterious and mysterious thing like attention.

The role of dreams is not to aggressively choose to emphasize those strong emotions or the most favorable thoughts, but rather a process of self-a**. In dreams, we associate some emotions with some symbols, and then dilute those emotions and leave them in our upbringing so that we don't stay in a state of emotional excitement and mood ups and downs. It's also an evolutionary advantage:

Through this regular self**, our ancestors have lived and evolved from all kinds of trauma to the present day.

Dreams are the most creative state of consciousness we humans have. It is a combination of chaotic, random cognitive elements that give rise to a new form of information: creativity (or new ideas).

Even if many, if not most, of these new ideas are meaningless, if a few of them are really useful, then the time we spend dreaming is not wasted.

People dream almost every day, but most of them you forget when you wake up. I haven't woken up much in years, and I haven't felt like I'm dreaming. But every time I wake up at night, I often find myself dreaming.

Sleep is broadly divided into three stages: light sleep, deep sleep, and REM sleep, and dreaming occurs during REM sleep. At this stage, δ waves disappear, high-frequency and low-amplitude brain waves similar to waking appears, the eyes begin to move rapidly up, down, left and right, and dreams begin to appear. Then repeat the three phases of sleep again.

But not every sleeper can reach the REM sleep stage, and not every sleep cycle can reach this stage. Some people don't sleep enough to reach this stage. In addition, the dreams that are generally remembered are awakened by the person during the REM sleep stage, and the other stages of awakening are generally not remembered.

Some people often dream when they sleep, because some people's brains are too excited during the day, so that they think about a lot of things before going to bed, which will also cause a lot of dreams. The reason why some people don't dream when they sleep is that their sleep quality is very good, and they are basically in deep sleep. Dreaming is a common thing, but dreaming too much is not a good thing.

Everyone dreams, and there is no such thing as a person who never dreams. Some people rarely dream because they are in a deep sleep. Many people dream at night and wake up during the day and forget about it, thinking that they are not dreaming.

Some people feel like they are dreaming at night, but I don't remember what I did during the day, and when I wake up, I forget 95% of my dreams. Therefore, when many people describe their dreams, they will say that they don't remember, the dreams they have at night are disappeared by the brain, people have no memory function when they dream, and they seem to be dreaming when they wake up during the day, but they don't remember the specific content.

Dreaming does not pose a threat to human life. If you have a good dream, your mood will improve during the day. Waking up from a nightmare will be upset.

Moreover, normal people will dream, some people will have different kinds of dreams at night, and the normal sleep is about 7-8 hours, maybe a third will be spent in dreams. Human sleep generally goes from light to dark, followed by rapid eye movement sleep, and the last step is related to dreams, the person's pupils move back and forth, and the brain is the same as when he was awake during the day, compared to deep sleep, the heart rate and breathing at this time will also change. It can be seen that dreaming is not an absolutely bad or good thing, most of the time it is a psychological reaction during the day, and there is no need to worry too much.

To sum up, some people will dream a lot when they sleep, and some people will not because they are in a deep sleep and have a good quality of sleep, so they will not dream. If you dream a lot at night, you spend less time in deep sleep than others, and if you dream a lot at night, you often feel sleepy during the day, so keep a good attitude. Bad habits to quit before going to bed.

The bad thing is mainly because everyone's situation is different, because some people are more stressed, so they also dream at night.

Because everyone's brain wave activity is different, some people can dream and some people can't. But if you dream a lot, it's definitely a bad thing.

Because everyone's growth and development are different, and people who dream more are caused by poor sleep quality, and dreaming more is a bad thing.

It is related to everyone's physique, and some people are prone to thinking too much, and they may dream. It's supposed to be a bad thing, it makes you very tired.

When we sleep, we all know that the quality of sleep is good and bad, and then sleep is also divided into deep and light sleep.

If you feel like you're dreaming all night while you're sleeping, it means that you're not asleep mentally, you're physically asleep, but you may not be sleeping well. In this way, when you wake up the next day, you will feel as if you are still listless, so you must calm down before going to bed, don't think too much, put down the day's work, and fall asleep smoothly, a quiet environment is the standard of sleep quality.

It's not uncommon to hear people complaining"I dreamed all night and didn't rest all night"，"I dreamed a lot at night, and I simply didn't fall asleep"。So is it really a dream that delays the rest? Is dreaming a sign that the brain is not resting or resting badly?

This notion is incorrect, dreaming and being able to recall dreams is not an indicator of not sleeping deeply, nor can it be said that dreaming does not mean that you have not slept well. Actually, dreaming is a physiological phenomenon, and whether you have a dream memory or not, you are determined to dream 4 or 5 times every night. Therefore, it is unrealistic to dream all night or not at all, and it is not possible to dream more or less.

There is no correlation between the feeling of dreams and the degree of insomnia. In other words, neither the presence or absence of dreams nor the degree of dreaming can be used as objective indicators of insomnia or the degree of insomnia.

Dreaming is a normal and essential physiological and psychological phenomenon of the human body. After a person falls asleep, a small part of the brain cells are still active, which is the basis of dreams. With the progress of modern psychology, the study of dreams has become more and more in-depth, and the mystery shrouded in dreams for thousands of years has been gradually lifted.

Psychologists believe that human intelligence has great potential, generally only less than 1 4, the other 3 4 is hidden in the unconscious, and dreaming is a typical unconscious activity, through dreaming can recombine the existing knowledge, the new knowledge and the old knowledge are reasonably integrated, and finally stored in the warehouse of billions, so that the knowledge becomes their own wisdom and talent. Dreams can help you think creatively, and many of the fruitful achievements of famous scientists and writers have also benefited from dreams.

A person's sleep, regardless of the length of time, always consists of periods of normal and heterophase sleep that alternate repeatedly. Since everyone has several periods of heterogeneous sleep, everyone dreams, and there must be dreams every night. In other words, dreaming is normal.

Dreams only occur during heterophase sleep, not during normal sleep. Each night, periods of normal-phase sleep and periods of heterogeneous sleep alternate several times. Always sleep at night, dream, lack of energy during the day, always feel sleepy, this is due to the lack of sleep depth at night, resulting in poor energy recovery, dreaming does not mean that you are not asleep, but problems occur after the third period of sleep.

It is recommended to go to the Department of Sleep Medicine or Psychology to understand the sleep pattern at night through sleep monitoring, and to improve the current sleep state through medication.

Dreaming doesn't mean you haven't slept well. It's just a dream.

The quality of sleep can be simply related to whether the body is comfortable when you wake up the next morning. Many people dream a lot, and the quality of sleep has nothing to do with it.

Hello, dreaming is equivalent to a bad quality of sleep.

No, it's just that the quality of sleep is not good.

Because many people do not enter a state of deep sleep when they sleep, they are in a light sleep when they are hungry, and at this time, the cerebral cortex of people is in a relatively active state, and there is a rotten source of dreaming.

This is very normal, when people are sleeping, the brain is more active, and this situation will occur, thinking day and night.

It may be stress, nervousness, thinking about more things during the day, or poor sleep quality.
