Why do people dream to fall? The benefits of dreaming

This phenomenon is not a dream, not to mention a ridiculous long man. Everyone has encountered this situation, including animals. It belongs to the normal physiological protection mechanism. When people sleep, their heart rate will decrease. When they sleep too deep, when their heart rate drops to too low, the brain detects abnormalities and thinks that you are going to die, so it activates the protection mechanism, sends out stimulus signals to wake you up and avoid sudden death When you sleep when you are too tired, you are most likely to fall and wake up. If you don't believe it, you can try to hold your breath for 1 minute. When your brain detects the danger, it will force you to breathe. For example, when people's body temperature is too low, blood will flow to the brain and heart to protect important organs. Therefore, there will be cold limbs. The human brain is very complex and has a self-protection mechanism. It's OK.

The benefits of dreaming

1. We know that if you have a good dream the night before, you will feel energetic and comfortable the next day. However, if you have a nightmare, you will feel unhappy the next day. If you don't sleep well, you will feel anxious, irritable and irritable. You can't calm down. It can be seen that dreaming is an essential link to maintain a good attitude.

From the perspective of psychoanalytic psychology, the meaning of dreams lies in the satisfaction of desire. No matter you are a noble person or a humble person, there are too many desires that are willing or able to speak and those who are unwilling or unable to speak out. Many of these almost endless desires cannot be satisfied immediately or at all in unrealistic life. The desire that can not or can not be satisfied in real life can obtain psychological satisfaction in dream and adjust psychological balance.

If there is no dream, then the big and small desire will make us unable to sleep soundly. Even if we sometimes feel uneasy and anxious in our dreams, we can make dreams and sleep the same.

2. Relieve fatigue and take a rest

Fatigue is the exhaustion of energy after physical and mental activities. The energy of brain mainly depends on blood supply of glucose. Physical and mental activities need a lot of glucose, if the blood supply of glucose can not meet its needs, this time it will use the body's reserves. The 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 fatigue. Sleep, all activities stopped, muscle consumption also decreased, in order to save energy, body temperature also decreased.

When people sleep, there is another function, is to synthesize new proteins. Most of the new proteins that the human body needs are synthesized during sleep. So sleep is essential to relieve fatigue and rest the body.

3. Organize information and bring insight

During the day, we experience a lot of things. Our brain should record, monitor and record what happens around you from time to time.

Whether you are conscious or unconscious, especially the amount of visual information is large, as long as you scan your eyes, all the stimulation will go to your brain. When you sleep, the brain will play back, while playing back, while sorting, and then according to different content, respectively put it in different functional circuits of the brain.

In addition, the brain also has the function of learning at night. For example, a well-known case in the west, detectives can't figure out how it happened during the day. As a result, he had a dream at night. What happened when the dream came out? The next day, according to his dream, he solved the case. In sleep at night like this, dreams sometimes bring insight and sometimes creativity.
