Why is dreaming a positive thing?

When we discussed the two states of sleep earlier, we made a detailed analysis of some physical conditions that occur during sleep. Dreaming is a normal physiological and psychological phenomenon in the human body. What does it mean if you don't dream?

Scientists have conducted some experiments to block people from dreaming, testing sleepers 'brain waves and waking them up when they go to sleep to stop them from continuing to dream. After conducting this experiment for a long time, the data showed that disrupting a person's normal dreaming state would destroy the body's functional reactions, such as blood pressure, pulse, body temperature, and skin's electrical responsiveness, while the function of the autonomic nervous system was weakened, and adverse psychological reactions frequently harassed, causing anxiety, tension, irritability, sensory hallucinations, memory disorders, disorientation, etc. Obviously, the quality of sleep is directly one of the important factors in ensuring the normal vitality of the body.

When people dream, activity in the right hemisphere of the brain is dominant, while when they are awake, the left hemisphere is dominant. Therefore, for 24 hours a day, humans need activity and sleep, so that awakening and dreams can alternate, which can promote neural regulation and mental activity. Dynamic balance. Therefore, dreams are a way to coordinate the balance of the human psychological world, especially having a more obvious effect on people's attention, emotions and cognitive activities.

If we really don't dream during our sleep process, it probably means that we have been in normal sleep, and people are not really resting at this time. Dreamless sleep is not only of poor quality, it is also a sign of brain damage or disease. Recent research results have also confirmed this view. Many people do not dream when they sleep. It may be because the brain's regulatory center is damaged and dreams cannot be formed, or only some incomplete dream fragments appear. If you sleep without dreams for a long time, it is worthy of people's vigilance. Of course, long-term nightmares are often a sign of weakness or certain diseases.
