Why do humans have dreams when they sleep? What’s the point of dreaming?

As we all know, all creatures have their own biological clocks, that is, they have time to rest and sleep. Although human beings are intelligent life, our body is not omnipotent. We also need to rest for a certain amount of time every day.

Research shows that one third of human life is sleeping, and a small number of people, due to work or other reasons, may sleep longer in their life. When we rest and sleep, it often happens that we dream.


Every one of us dreams, which is a natural physiological phenomenon. If a person can’t dream, it means that his body may have problems, or life is coming to an end. In many people’s eyes, dreaming is a very normal physiological phenomenon, which is not strange and has no research value.

But in the cognition of scientists, it is different. In fact, in ancient times, some wise people began to think and study, what’s the matter with dreaming? I believe many friends know the story of the famous Zhuangzhou Mengdie, and Zhougong jiemeng is also a guess of the ancients to explain the content of the dream.

The ancients’ interpretation of dreams tends to be more mythological. From a scientific point of view, there are no gods and ghosts in this world. So from a scientific point of view, what’s the matter with dreaming? Why do humans have dreams when they sleep? What’s the point of dreaming?


You know, the human body is a very complex and mysterious life, especially the brain is the core. The reason why human beings can be different from other animals is intelligent life is that we have a developed intelligent brain. Since the brain is the core of human beings, every manifestation of it cannot be meaningless. All kinds of dreams in the brain are bound to represent some meaning for human beings, so what is the meaning?

The scientific exploration and research of dreams has already begun since human beings entered the era of science and technology. As early as the 1970s, that is, more than 50 years ago, scientists understood that human sleep includes two stages: slow wave sleep and rapid eye movement sleep. These two stages will dream, and there will be dreams.


In order to explore the mystery of dreams, psychologists and neuroscientists have made a lot of efforts. In the view of psychologists, dream is a kind of reaction in real life. It is a reflection of the day and a dream of the night. The greater the stress in real life, the higher the frequency of dreaming.

We should know that with the continuous progress of science and technology, although people’s living standard is higher and higher, people are also facing more and more pressure. If the pressure during the day can not be effectively released, it will inevitably affect the next day’s work and even affect health. Dreaming is a better way to release the pressure of reality, which may be a self-regulation function of the brain to the body.

Psychologists believe that dreaming is a kind of stress, so is it really true? Neuroscientists don’t agree with this view. Yes, some dreams do have something to do with reality. When you think about it every day, you will also have some performance when you dream at night. But not all dreams can be associated with reality.


I believe many friends have had many dreams, some of which are really reflected in their own daily thoughts, but quite a few of them are very strange, and do not seem to have a certain relationship with reality. For example: some friends do software programming, because of the pressure during the day, they may have some dreams related to software programming at night, but sometimes the dreams have nothing to do with this, and even you will have some dreams of other industries, such as becoming an astronaut, becoming a doctor and so on.

You don’t think about these strange dreams in your daily life, that is, you don’t have the ideal of being an astronaut, and you don’t want to be an astronaut. But in your dream, you become a glorious astronaut. This kind of dream, which has nothing to do with thinking about the day, accounts for a large proportion of all dreams. It is not entirely correct to say that thinking about tomorrow and dreaming about night.


If dreams are not the representative of pressure or the result of thinking deeply, how do they come into being? What does it mean to human beings? In 2000, Anta rayonso, a psychologist and philosopher at the University of Turku in Finland, put forward an innovative theory. He believed that dreams are used to simulate a dangerous situation, and dreams can help people learn to face danger better.

Through research, rayonso found that many people have images of attack, chase and danger in their dreams. When we face all kinds of dangers in our dreams, our performance is often excellent. For example, your body is very agile, your running speed is very fast, and you can even fly like superman.

I believe many people have done this kind of dream. Xiaobian himself has done many dangerous scenes, such as facing attacks and chasing. In the dream, Xiaobian is full of incredible power, and all kinds of dangers can be easily avoided. Scientists believe that this is actually an important significance of dreaming for human beings, that is, to carry out all kinds of dangerous training, so that we can be personally on the scene in the three-dimensional world of dreams, and feel the emotions and reactions in the real environment.


We all know that the dream scene is very real. Sometimes we can’t tell whether it is a reality or a dream, so in this kind of near real scene, we can better train our senses and motor organs. And it can form a kind of memory for us to face all kinds of dangers in our dreams. If the same danger happens in the real world, we can quickly make the right way to deal with it.

Some scientists believe that dreams can better digest negative emotions. We often say that there is a devil in everyone’s heart, and this devil is the negative emotions of human beings. Because everyone has work, life and other pressures, under the influence of various pressures, there will be varying degrees of negative emotions.


These negative emotions are stored in people’s heart. Once they accumulate to a certain extent, they may completely burst out and make a person’s character change greatly. The birth of negative emotions is very difficult to avoid, unless you live in the mountains and have no contact with the outside world.

As long as we have contact with the real society, then the emergence of negative emotions is inevitable, while dreaming can effectively eliminate and digest these negative emotions, so that we always maintain a positive and optimistic attitude. Through some research, scientists have found that dreams during REM sleep are especially prone to be filled with negative emotions, because the amygdala (the emotional center of the brain) is very active during this stage.

In this sleep stage, the brain’s special configuration allows it to “idle” to better adapt to the recorded images and emotions. The fear or difficulty emotion generated the day before is combined with some other possibly unrelated and more neutral things in order to better “digest” these negative emotions. This is the reason why some unrelated things in dreams are strangely connected. So the shortest way from despair to hope is to have a good sleep.


Scientists also found that dreams can reconstruct and reproduce the real events that happened the day before, thus deepening the memory of the events. Many experiments have confirmed that sleeping for a period of time after learning can improve the quality of learning, which is deeper than keeping awake memory for the same period of time. This is also an important significance of dreaming, that is to improve memory and learning effect.

Through the above analysis and research, we will find that dreaming is not meaningless, on the contrary, it is of great significance to human beings. Generally speaking, the brain makes us dream when we sleep for the good of human beings and for the better development of human civilization. This once again makes us realize the greatness and mystery of the brain, and there are still many mysteries about dreams that have not been solved. Only when the future technology advances, can we really solve all the mysteries of dreams.
