A: There are several reasons for dreaming at night. First, when people are under great mental pressure or influenced by good or bad things, they feel that some things can't be let go, leading to excessive excitement in the cerebral cortex and MUBI at night. Second, eating too much at night will make the brain reflect all the time, leading to MUBI. Third, improper sleeping posture, such as pressing the heart and respiratory and circulatory system, and uncomfortable bedding, such as being too light and too heavy, will lead to MUBI. Fourth, too little sleep makes the brain not rest well, which leads to MUBI. Fifth, there is something wrong with the digestive system, which stimulates the brain and leads to MUBI. Sixth, with the symptoms of neurasthenia, it is bound to show MUBI. You can see what kind of situation you belong to and then take appropriate measures. Remember that the fifth and sixth situations are to go to the hospital to find a doctor.
