The relationship between weather and dreaming

There is a certain relationship. For example, if the weather is very hot, you may dream about fire.

The weather has temperature, and the human body senses the temperature and sends a signal to the brain. In Dream consciousness will have an impact!

According to relevant information, a person spends about 1/3 of his life sleeping and 1/5 of his life dreaming. If a person lives for 75 years, then he will be dreaming for 15 years. Do you know, why do people dream?

As the saying goes: "Think about it during the day and dream about it at night." The source of dreams is actually the activity of the brain. We know that when people's brains are awake, they , able to respond continuously to external stimuli. At night, people are tired and go to sleep. During most of the sleep process, brain waves, eye movements, etc. are the same as when they are awake, and only the body muscles are in a suppressed state. At this time, things we have experienced, seen or thought about during the day will appear in our dreams.

The content of dreams is often related to the stimulation received during the day or while sleeping. If you think too much about a certain thing during the day, you will dream about it when you sleep at night. Or, although you have not thought about someone or something before, some nerve cells in your brain will "recall" it when you sleep at night because you have experienced it before. The past happened, so I would dream about it.

While sleeping, external stimulation will cause the brain to react incorrectly, leading to all kinds of weird dreams. In addition, stimulation and pathological changes of various organs in the body will cause similar scenes to appear in dreams. For example, if you are in a hurry to urinate and defecate, you will dream that you can't find the toilet anywhere, etc.

Dreaming is a physiological phenomenon. Normal dreaming will not affect your health, but if you often have nightmares or strange dreams that affect your sleep, you should see a doctor for timely treatment. 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

Pavlov said: "Dreaming is a kind of trace stimulation, and most of it is old traces of excitement. ". 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. When a person's eyes move, it means that the sleeper is dreaming. Nowadays, when people study the physiology of dreams, they use the number and time of eyeball movements to measure the number of times people dream and the length of dreams. However, there is also a saying that human sleep is always in a rhythmic cycle, that is, in the alternation between rapid eye movement sleep and slow wave sleep. Slow wave sleep is a quiet sleep state, while in rapid eye movement sleep, people's eyes will also move rapidly due to irregular breathing and heart rhythm. 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 appear alternately, which can achieve a dynamic balance of neural regulation and mental activity. Therefore, dreams are a way of coordinating the balance of the human psychological world, especially 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.
