Why do people dream? What is the meaning of dreams? What impact do dreams have on people? Dreamologists, psychologists and neurobiologists have been searching for this for thousands of years. However, they have still not been able to find an answer to this question.

The answer to the riddle.

The more rigorous scientific research on dreaming began in the 17th century.

In 1886, dream expert Robert believed that people are exposed to countless information intentionally or unintentionally during a day's activities, and part of this information must be released through dreams. This is the famous "dreaming is to forget" theory. This theory is used in

A hundred years later, it became popular again in the 1980s.

Soon after Robert, Freud's psychological dream interpretation theory appeared. Freud believed that people are constantly generating wishes and desires, and these wishes and desires are expressed and released in dreams through various disguises and deformations.

, so as not to break into people's consciousness and wake them up. In other words, dreams can help people eliminate those wishes and desires that the conscious system cannot accept, and are the guardians of sleep.

Freud's theory was popular from the beginning of this century to the 1960s. Later, the world's research on dreams slowly left the field of psychology and entered biological laboratories. Dreaming has since been regarded as a biological phenomenon.

Michel Jouvat, a neurobiologist at the Dream Science Laboratory in Lyon, France, is an internationally renowned expert in dream science. In 1959, Jouvat defined dreams as "abnormal sleep."

Through electroencephalogram testing, he found that people have 5 to 20 minutes of dreaming sleep every 90 minutes. The signals reflected on the screen of the instrument are different, showing the changes in brain activity during sleep.

If the person being tested is awakened when the electroencephalogram wave shows dreamless sleep, he will say that he did not have any dreams; if he is awakened when the electroencephalogram wave shows dreamless sleep, he will remember the dream he just had.

In addition, researchers used X-ray tomography tests and found that the image of the brain during the dreaming sleep stage is close to the image when awake.

Interestingly, researchers used instruments to test and found that dreaming is not a unique phenomenon for humans. Birds and all mammals also dream.

In the late 1970s, a scientist discovered through experiments on mice that dreaming sleep is also related to memory. Dreaming mice can remember experiences better than mice deprived of dreaming sleep. However, this research result does not apply to humans because doctors

In the treatment of depressed patients, a drug called a single ammonia oxidase inhibitor is used. This drug completely cancels the person's dream sleep, but does not cause memory disorders.

French dream science expert Jouvat believes that dreaming is determined by genetic genes. He compared the signal numbers sent out by mice during dreaming sleep and found that mice with the same genetic system have similar signal numbers. This theory was recently announced by the United States

An experiment by Bulga, a researcher at the University of Colorado, confirmed this.

Burga conducted a study on identical twins and found that the twins who were raised by two different families in different places actually had similar dreaming experiences. This proved that people's dream performance is a genetic memory.

In addition, there is a latest report on dreaming research in the just-published American "Science Weekly". The author of the report, a collaborative team from the Washington Institute of Neuroscience and the National Institute of Health in Bozestadt, Maryland, used a high-performance neural tomography machine to

The camera was tested on a dozen people who were subjected to the experiment, and it was found that blood circulation in this specific area of ??the cerebral cortex was abnormally accelerated during the dreaming sleep stage. From this, the researchers discovered that the brain is responsible for seeing dream scenes and external vision.

The visual nervous system of the scene originally existed independently.

The report said that after the inner vision system of dream viewing is confirmed to exist independently, it will be able to explain why we have expanded emotions in dreams and why we can accept those unreasonable and bizarre plots and disordered concepts of time and space.

Dreaming is a normal and essential physiological and psychological phenomenon of the human body.

After a person falls asleep, a small number of brain cells are still active, which is the basis of dreams.

Why do people dream, and what will happen if they don’t dream?

Normal dream activity is one of the important factors to ensure normal vitality of the body. Scientists have done some experiments to block people's dreams.

That is, as soon as the dreaming brain waves appear in the sleeper, the sleeper is immediately awakened and does not allow the dream to continue. Repeatedly, it is found that deprivation of dreams will lead to a series of physiological abnormalities in the human body, such as blood pressure, pulse, body temperature, and skin.

The electrical response ability of people tends to increase, and the function of the autonomic nervous system is weakened. At the same time, it can also cause a series of adverse psychological reactions in people, such as anxiety, tension, irritability, sensory hallucinations, memory impairment, disorientation, etc.

Obviously, normal dream activity is one of the important factors in ensuring the normal vitality of the body.

Dreams are a way of coordinating the balance of the human psychological world. Because the right brain hemisphere is dominant in dreams, and the left brain hemisphere is dominant after awakening, during the body's 24-hour day and night activities, waking and dreaming alternate.

Appear, can achieve the dynamic balance of neural regulation and mental activity.

Therefore, dreams are a way of coordinating the balance of the human psychological world, especially having a significant effect on people's attention, emotions and cognitive activities.

Dreamless sleep is not only of poor quality, but also a sign of brain damage or disease. Recent research results have also confirmed this point of view, that is, dreams are the result of the brain's regulatory center balancing various functions of the body. Dreams are a sign of healthy brain development and

The need to maintain normal thinking.
