Seek dreams! Death game nightmare.

The origin of dreams: during sleep, brain cells are basically in a static state, and only a few are still weak and active to a certain extent. Because this activity is basically unaffected by perception and not controlled by rational thinking, it has formed the characteristics of strong imagery and weak logic of dreams. If the activity of these brain cells is too weak or slack, dreams cannot be formed. However, when there is some abnormality in the body, the number of brain cells at rest during sleep decreases, and there are many disturbances from waking factors. At this time, the relationship between the dream formed and the state of mind when awake has increased, which is what people often say, "thinking day and night."
