Duke Zhou said: If you dream that your sister drowned, you will live a long life. Don't think the worst, okay?
Psychological explanation of dreams: Dreams are spontaneous psychological activities at a certain stage of human consciousness during sleep. In this kind of psychological activity, the whole process of individual physical and mental changes is called dreaming. Dreams are only the image activities of deep cells in the cerebral cortex during sleep due to internal and external stimuli, which have no practical significance.
