Why is the dream strange, but it will come true one day?

Why do people dream, what is the meaning of dreams, and what effect do dreams have on people? For thousands of years, dreamers, psychologists and neurobiologists have been looking for this, but so far they have failed to find the answer to this mystery.

More rigorous scientific research on dreaming began in17th century. 1886 Robert, an expert on dreams, believes that people are exposed to countless information intentionally or unintentionally in their daily activities, and they must release some of these information through dreams. This is the famous theory that "dreaming is to forget", which began to be popular again in the1980s one hundred years later. Shortly after Robert, Freud's theory of psychological dream interpretation appeared again. Freud believed that people constantly have desires and desires, which are expressed and released through various disguises and deformations in dreams, so that they will not break into people's consciousness and wake people up. That is to say, dreams can help people eliminate those desires and desires that are unacceptable to the conscious system and are the guardians of sleep protection. Freud's theory was popular from the beginning of this century to the 1960s. Later, the study of dreams in the world slowly left the field of psychology and entered the biological laboratory. Since then, dreaming has been regarded as a biological phenomenon. Michel Jouvet, a neurobiologist at the Dream Research Laboratory in Lyon, France, is an internationally renowned expert in dream research. Jouvet defined dreaming as "parasomnia" in 1959. He found through EEG test that people have 5 ~ 20 minutes of dreamy sleep every 90 minutes, and the signals reflected on the instrument screen are different, showing the changes of brain activity during sleep. If the subject is awakened when the EEG shows dreamless sleep, he will say that there is no dream; If you wake him up when he shows dreamy sleep, he will remember the dream he just had. In addition, the researchers used X-ray tomography technology to test and found that the image of the brain in dreamy sleep stage is close to that in waking state. Interestingly, the researchers found that dreaming is not unique to human beings, and birds and all mammals also dream. In the late 1970s, a scientist discovered through experiments on mice that dreamy sleep was also related to memory. Dreamy mice can remember their experiences better than those deprived of dream sleep, but the results of this study are not applicable to humans, because doctors use an inhibitor called monoamine oxidase when treating patients with mental depression, which can completely cancel people's dream sleep, but will not cause memory impairment. Wei Ru, a French expert on dreams, believes that dreams are determined by genetic factors. He compared the letters and numbers that mice emit when they sleep in dreams, and found that mice with the same genetic system have similar letters and numbers. A recent experiment by Bulga, a researcher at the University of Colorado in the United States, confirmed this theory. Bulga studied identical twins and found that twins who were raised by two different families in different places after birth actually had similar dream experiences, which proved that human dream performance is genetic memory.

In addition, there is a recent report on dreaming research in the just published American Science Weekly. The author of this report, a cooperative team of the Washington Institute of Neuroscience and the National Institute of Health in Bocaistar, Maryland, tested more than a dozen people who accepted the experiment with a high-performance neural tomography camera and found that the blood circulation in this specific area of their cerebral cortex was abnormally accelerated during the dream sleep stage. The researchers found that the visual nervous system responsible for seeing dream scenes and external visual scenes in the brain originally existed independently. According to the report, after seeing that the internal visual system of dreams has been proved to exist independently, it can explain why we have inflated emotions in dreams and why we can accept unreasonable eccentric plots and chaotic concepts of time and space.

Dreaming is a normal and indispensable physiological and psychological phenomenon of human body. After people fall asleep, a small number of brain cells are still active, which is the basis of dreaming. Why do people dream and what happens if they don't dream?

Normal dream activity is one of the important factors to ensure the normal vitality of the body.

Scientists have done some experiments to stop people from dreaming. That is to say, when the sleeper has a dream brainwave, he is immediately awakened to stop his dream from continuing, and so on. The results show that deprivation of dreams will lead to a series of physiological abnormalities of human body, such as blood pressure, pulse, body temperature and skin electrical response ability, and the function of autonomic nervous system will be weakened. At the same time, it will also cause a series of adverse psychological reactions, such as anxiety, tension, irritability, perceptual hallucinations, memory disorders, irritability and so on. Obviously, normal dream activity is one of the important factors to ensure the normal vitality of the body.

Dreams are a way to coordinate the balance of human psychological world.

Because the right hemisphere is dominant when dreaming and the left hemisphere is dominant after awakening, the dynamic balance between nerve regulation and mental activity can be achieved by alternately waking up and dreaming during the 24-hour day and night activities of the body. Therefore, dreams are a way to balance people's psychological world, especially for people's attention, emotions and cognitive activities.

Dreamless sleep is not only of poor quality, but also a sign of brain injury or disease.

Recent research results also confirm this view, that is, dreams are the result of the brain's regulatory center balancing various functions of the body, and dreams are the need for the healthy development of the brain and maintaining normal thinking. If the brain's regulatory center is damaged, dreams will not form, or only some incomplete dream fragments will appear. If you sleep for a long time without dreams, it is worth people's vigilance. Of course, if you have nightmares for a long time, it is often a sign of weakness or some diseases.

Dreaming can produce extremely active chemical reactions in the brain, leading to the peak of protein synthesis and renewal of brain cells, while fast-flowing blood brings oxygen and nutrients, and takes away waste, so that brain cells that cannot self-renew can quickly update protein components, preparing for intense activities in the future. Therefore, to some extent, dreaming contributes to brain function.

Some cells in the brain don't work when awake, but when people fall asleep, these cells are "practicing" their own functions, so dreams are formed. Dreams give people painful or pleasant memories. Dreams exercise the function of the brain. Dreams can sometimes lead you to change your life, and can also partially solve the conflicts when you are awake, making your life more fulfilling.

Speaking of which, I am in the same situation as the landlord. Even sleeping secretly in class can dream. But there seems to be no obvious evidence that frequent dreaming leads to insufficient sleep, so don't worry too much.

If you want to know more details, you can read the following article:

Almost everyone dreams when they sleep. Dreams can be divided into meaningless dreams, sweet dreams and nightmares. Adults usually dream 3-6 times a night, lasting two hours in total, less in the early stage of sleep and more in the late stage of sleep.

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 introduced into the brain through the sensory system, arousing the "awakening state" of some cell groups in the brain, thus dreaming. This means that some areas of the brain can still keep in touch with external stimuli during sleep, which is dreaming.

Dreaming can produce extremely active chemical reactions in the brain, leading to the peak of protein synthesis and renewal of brain cells, while fast-flowing blood brings oxygen and nutrients, and takes away waste, so that brain cells that cannot self-renew can quickly update protein components, preparing for intense activities in the future.

Sweet dreams often bring people pleasant, comfortable and relaxed feelings, make people clear-headed, enhance their thinking activities, contribute to people's digestion and physical and mental health, help stabilize people's emotions, promote and improve people's intellectual activity ability, and sprout inspiration and creative thinking. It is no wonder that people in some countries and regions still regard "sweet dreams" as a pet phrase to say hello before going to bed.

Nightmares not only make people unhappy, but also interfere with sleep and affect the functional activities of the brain. In addition, nightmares are often early signs of cancer and other diseases. In particular, frequent and repeated nightmares with roughly the same content can predict obvious symptoms of the disease, reveal the location, nature and severity of the disease, and make predictions a few days, a month or even a year before the patient's external symptoms are revealed.

Nightmares have psychological, physiological and pathological reasons. Mental depression, many physical diseases and indigestion can all lead to nightmares. For people with severe heart disease, cerebral arteriosclerosis and cerebral aneurysm, nightmares are more likely to induce and aggravate serious diseases such as heart failure, myocardial infarction, cerebral hemorrhage, cerebral infarction and subarachnoid hemorrhage. It can be seen that nightmares have adverse effects on intelligence, physical strength and health, and should be avoided as much as possible. Even if you don't have nightmares, if you have a lot of dreams during the whole night's sleep, but you remember them clearly, it is also a kind of sleep disorder, indicating that the inhibition process of his brain is too shallow, which will inevitably affect the elimination of emotions and fatigue, and will also make you sleepy during the day, and it is difficult to concentrate, which will seriously affect normal study and work.
