How does nightly dream do nightly often dream is ill?
Dream is a kind of illusory feedback when the brain is resting. In our daily activities, our brain will deal with all kinds of complex information. In the process of sorting out huge information, the memory of some things will be reflected in the brain, which is another thinking state when the brain is resting. So how is it that you often dream at night? Is it that you dream at night?
More dreams, less dreams:
According to the research, people's sleep is carried out alternately by the two forms of positive sleep and heterogeneous sleep. 80% of the people who are awakened in the heterogeneous sleep are dreaming, and 7% of the people who are awakened in the positive sleep are dreaming. A person's dream can last about 1.5 hours every night. Because dreams accompany the regular cycle of sleep cycle, people who wake up in the abnormal sleep feel more dreams, while people who wake up in the normal sleep feel less dreams. In addition, people can remember more dreams when they are about to wake up, and the dreams just falling asleep have long disappeared, which is another reason why people feel more or less dreams.
Abnormal sweating:
According to traditional Chinese medicine, the basic reason for multiple dreams lies in the internal changes of the body. It is recorded in ancient books that lack of Qi and blood, damage of emotions, deficiency of yin and blood, disturbance of liver and gall due to phlegm and heat, overwork, incoherence of diet and other reasons will lead to multiple dreams. In modern medicine, neurasthenia, a lot of mental labor lead to over excitation of brain nerves, incorrect sleeping posture and insomnia.
No dream:
Dreamless sleep is not only of poor quality, but also a sign of brain damage or disease. Clinicians have found that some patients with headache and dizziness often tell that they have no dreams or rarely dream in sleep. After diagnosis and examination, it is confirmed that these patients have slight hemorrhage or tumor in the brain. Medical observation shows that children with dementia have significantly less dream sleep than normal children of the same age, the elderly with chronic brain syndrome have significantly less dream sleep than normal elderly of the same age.
Recent research results also confirm the view that dreams are the result of the brain regulating center balancing various functions of the body, and dreams are the need of the healthy development of the brain and the maintenance of normal thinking. If the brain regulation center is damaged, dreams will not be formed, or only some incomplete dream fragments will appear. If there is no dream sleep for a long time, it is worth people's vigilance.
Nightmare:
Modern medicine has proved that nightmares are often the precursor signals of some diseases of the human body, which can remind people of their vigilance to diseases as early as possible. The stimulation of human pathological changes is often reflected in dreams. When people are awake, the weak stimulation of disease is mostly covered by various external stimulation. After going to sleep at night, the amount of information transmitted by the outside world to the human body is greatly reduced, while the stimulation from the internal organs takes advantage in the brain, thus causing the unconscious vigilance and response.
The detailed explanation of nightmares in human sleep period in modern medicine: the decline of body and viscera function or the existence of latent diseases. The cause of sudden heart failure is the precursor, tachycardia or bradycardia. The nervous system of the brain is stimulated by powerful external information. The influence of chemicals in the natural environment on the viscera and organs of human body. The change of living environment can lead to the decrease of people's mental capacity.
