Why do people dream

When people sleep, the brain is also at rest, but the rest process of the brain is not complete, a part of the cerebral cortex cells are still very active, resulting in some nerves are still in an excited state, resulting in a dream. In addition, the external environment can also cause dreams, such as the bed overheating or physical illness, can also cause dreams. Some people still have some consciousness in their dreams and can even think logically.

Ancient people from the perspective of traditional Chinese medicine to discuss why people will dream, some doctors believe that the lack or excess of Yin and Yang qi in the body, the five viscera qi excessive, qi and blood excess or suffering from some kind of disease, will lead to dreaming. In addition, from the perspective of psychological factors, if people think excessively during the day, or encounter great joy and sorrow, they will also dream.

Dreams are the companions of sleep. Dreaming is a normal and indispensable physiological and psychological phenomenon in the human body. When people fall asleep, a small part of the brain cells are still active, which is the physiological basis of dreams.

Why do people dream and how do they react when they don't dream?

Scientists have done some experiments to block people's dreams. When the sleeper appears the dream brain wave, it is immediately awakened, and the dream is not allowed to continue, and so on. The results show that dream deprivation can lead to a series of physiological abnormalities, such as abnormal changes in blood pressure, pulse, and body temperature, and the function of autonomic nervous system is weakened. At the same time, it can also cause a series of adverse psychological reactions, such as anxiety, nervousness, irritability, perceptual hallucinations, memory disorders and so on. That is to say, people need dreams. Dream activity is one of the important factors to ensure the normal operation of the human body.

Is there someone who doesn't dream? Most scientists believe that all humans dream. If someone thinks they have no dreams or very few dreams, it is because they have forgotten all about their dreams when they wake up. Studies have shown that dreamless sleep is not only bad quality, but also a sign of brain damage and disease. Recent scientific research results show that dreams are the result of the balance of various functions of the body in the brain regulatory center, which is the need for healthy brain development and maintenance of normal thinking. If there is no dream sleep for a long time, it is a phenomenon worthy of people's vigilance.

Scientists have carefully studied the relationship between dreams and sleep and found that dreams mainly occur during rapid eye movement sleep. What is REM sleep? This is a state of light sleep that occurs late in sleep and is characterized by rapid horizontal eye movements, increased breathing and heart rate, and temporary limb paralysis. If a person is awakened directly from REM sleep (by an alarm clock, for example), they will most likely report to you that they are having a vivid dream. In children or adults who are in REM sleep, about 60 to 90 percent of them report dreaming before waking up. The changes of organ function in the REM sleep cycle indicate that there is a certain physiological connection between REM sleep and dreams, or that the REM sleep period has more psychological and physiological basis for dream production. Dreams can also occur during other periods of sleep, but they are less frequent and more ambiguous.

Why do people dream? What does REM sleep do? A recent study found that REM sleep plays a role in improving people's ability to perform on newly learned tasks while they sleep. Scientists believe that REM sleep is an adaptive survival mechanism.

What is the meaning of dreams? The famous psychology master Freud made a pioneering solution to this problem, and published an epoch-making work 'The interpretation of dreams'. Freud believes that dreams reflect the desires in the depths of the human mind, located in the subconscious, and these desires are expressed through a certain camouflage and transformation, which forms a dream. Based on his analysis of dreams and the unconscious, Freud created a new school of psychology called psychoanalysis. Another master of the psychoanalytic school was the Swiss psychologist Carl Jung. Jung interpreted tens of thousands of dreams and had a profound understanding of the nature of dreams. According to Jung, 'Dreams are the spontaneous and undistorted product of the unconscious mind... Dreams show us the unadorned truth of nature.' In addition, the American psychologist Fromm also believes that dreams are a symbolic language with similar characteristics to myths.

Are dreams a uniquely human phenomenon? Do animals dream? True dreaming has only been directly proven to occur in humans, although many believe it occurs in other animals as well. Animals are well established to have REM sleep, but we can't ask animals to report their experiences. The animal with the longest periods of REM sleep on average is the pangolin. Mammals may be the only, or at least the most frequent, dreamers in nature because of their sleep patterns.

In addition to the dreams that occur during sleep at night, do you also dream during the day? For some people, especially teenagers, there may also be a psychological activity with a fantasy plot in the waking state, which is called 'daydreaming' in psychology, also known as 'reverie'. Psychologists believe that 'daydreaming' is an effective way to relax psychological nerves, and young people's 'daydreaming' is beneficial to both body and mind. Experts who study human mental health say that although the exact mechanism of 'daydreaming' affecting human physical and mental health is not yet clear, it is certain that this brain activity plays a benign role in promoting the immune system. In addition, 'daydreaming' can free the left side of the brain from language activities and be in a state of rest, so that the right brain can give full play to its intuitive image thinking ability, which can eliminate and alleviate the fatigue of workers who are good at language thinking and accustomed to using the right hand.

In addition to beautiful daydreams, people also have horrible nightmares.

What does it mean to have nightmares? Medical professionals believe that if the nightmares are persistent, it may be a sign of weakness or disease. Dreams are subconscious psychological reactions that everyone has. Although they may seem absurd, they can sometimes reveal clues about physical health. Psychologists believe that a dream is like a meter that responds to changes in the body that are not yet known to the conscious mind. For example, some hepatitis patients in the days before the onset of the disease will appear anxious, fearful dreams, and some patients complain of right rib injury pain in the dream. Nightmares may be a predictor of disease, therefore, long-term nightmares should cause our attention, you can consider consulting a doctor and do a physical examination.

Dreams are inseparable from daily life. Some dreams are often closely related to their own experiences, or are influenced by certain episodes in novels, television, and movies. Other dreams are caused by stimulation of certain parts of the body. For example, when stimulated by a full bladder, they often dream about the toilet. Another reason dreams are formed is a strong desire. When in love, the figure of the lover often appears in the dream. When you want to play somewhere, or want to eat something, you often get it in your dream. So, the famous Austrian psychologist Sigmund Freud proposed that dreams are the fulfillment of wishes.
