Clear. Li Yu's The Twelfth Floor. Seven Clouds: "How brave are you as a daughter? Many people must be afraid of gods and ghosts, and there is another saying that goes well:' Think day and night.' "

Many experiments by western scientists have also proved that if you encounter something exciting during the day, or you feel sad or afraid, it is easy to have related dreams when you sleep at night.
