Why do people dream? Is dreaming good for your health?

At night, when we are sleeping, our noise is still working, so many people will have the experience of dreaming, some dreams are sweet, some dreams are horrible, thinking of the day, and some dreams at night, so why do people dream?

We know that when sleeping, even when sleeping, the human body is not completely isolated from the surrounding environment. Some external stimuli can still be transmitted to the brain through the sensory system, to arouse the 'awakening state' of some cell groups in the brain and dream. That is to say, some areas of the brain in sleep can still maintain a certain connection with external stimulation, which is called dreaming.

Why do people dream?

Research shows that about one-third of human life is in sleep, and one-fifth of the time is dreaming. The so-called "thinking by day and dreaming by night" is not unreasonable. Dreams are brain activities after all. When the human body is awake, the human body can instinctively respond to external things. But in fact, when the human body is in a dormant state, not all organs also deal with the dormant state. Brain waves, eyeballs and so on are the same as when waking up, except that the muscles of the body are in a rest, at this time, the experience that happens in the daytime is likely to appear in the dream. In general, the content of dreaming has a lot to do with the experience or stimulation of the day. Some people will dream constantly when they are over emotional or working load for a period of time.

How many dreams is it normal to have every night?

Since dreaming is a normal physiological phenomenon, many people have more than one dream in a night. How many dreams are normal every night? In fact, 4-5 dreams are normal. It is unrealistic to say that dreaming all night or no dreaming, but the dream closest to waking up in the morning is quite impressive. There is no inevitable connection between dreaming and insomnia, nor can it be used to judge insomnia Basis.

How about dreaming often? Dreaming is not a bad thing!

Some people feel that the next day after dreaming is in a very bad state. There is no need to worry and panic psychologically. In fact, this is just a kind of self suggestion. The daily activities of human brain cells are limited to one part, and the other part is basically in a dormant state. If dormant brain cells are not used for a long time, they will gradually decline and weaken. For this part of brain cells, they often exercise themselves by dreaming. In fact, dreaming is also a state of human brain work. Night dreaming is often the collation of work information during the day. Sometimes, problems that cannot be solved during the day, dreams will give you solutions or hints. Normally, dreaming is good for sleep, except for nightmares and even waking up.

There are four benefits of dreaming

1. Psychological adjustment

We know that if we had a good dream the night before, we would feel energetic and comfortable the next day. But if you have nightmares, you will feel unhappy the next day. If you don't sleep well, you will feel anxious, fidgety, grumpy and restless. It can be seen that dreaming is an essential part of maintaining a good state of mind.

From the perspective of psychoanalytic psychology, the meaning of dreams lies in the satisfaction of desires. No matter you are a noble person or a humble person, there are too many desires in our deep heart that we are willing or able to say and unwilling or unable to say. Many of these almost endless desires can not be satisfied in real life or at all. In real life, the desire that can't or can't be satisfied can be met psychologically in the dream, and the psychological balance can be adjusted.

If there is no dream, then big and small desires will make us unable to sleep. Even if we sometimes feel uneasy and anxious in our dreams, we can also keep dreaming and sleeping together.

2. Relieve fatigue and take a rest

Fatigue is the exhaustion of energy after physical and mental activities. The energy of brain is mainly supplied by blood glucose. Physical and mental activities need a lot of glucose. If the glucose supplied from the blood can not meet its needs, it will use the body's reserves at this time. This process of using the body's reserves produces a form of lactic acid.

The accumulation of lactic acid is a physiological and biochemical manifestation of fatigue. Sleep can relieve this kind of fatigue. When I fell asleep, all my activities stopped and my muscle consumption decreased. In order to save energy, my body temperature also decreased.

When people are sleeping, another function is to synthesize new proteins. Most of the new proteins needed by the human body are synthesized during sleep. Therefore, sleep is essential to relieve fatigue and rest the body.

3. Organize information to bring insight

During the day we experience a lot of things. Our brain should record, monitor and record everything around you.

No matter you consciously or unconsciously, especially the amount of visual information is very large. As long as you scan your eyes, all the stimulation will run into your brain. When you sleep, the brain will play back, play back, and organize at the same time, and then put it into different functional circuits of the brain according to different contents.

In addition, the brain has the function of learning at night. For example, in a very famous strange case in the west, detectives can't figure out how it happened in the daytime. As a result, he had a dream at night. What happened when he came out of the dream? The next day, according to the clue of his dream, he solved the case. Like this kind of sleep at night, dreams sometimes bring insight, sometimes bring innovation.

4. Dreaming helps brain function

Dreaming can produce extremely active chemical reactions in the brain, and make the protein synthesis and renewal of brain cells reach the peak, while the fast flowing blood will bring oxygen and nutrients, and transport the waste away, which will make the brain cells that cannot renew themselves quickly update their protein components, so as to prepare for the intense activities in the future. So, in a way, dreaming helps brain function.

Some cells in the brain don't work when awake, but when people fall asleep, these cells' exercise 'their functions, and thus form dreams. Dreams give people painful or happy memories. They exercise the brain function. Sometimes dreams can guide you to change your life. They can also partially solve the conflicts when you wake up, which will enrich your life.
