Duke Zhou dreamed that he was flying.

Dreams are the expression of people's subconsciousness and the combination of many fragmentary subconsciousness. The images of these dreams often come from past experiences or media, imagination or sleep feelings, but there may be no memory in reality. Dreams string them together. Dreams are exaggerated (flying higher and higher on the ground), and the content of dreams is generally irrelevant to reality. But dreams can reflect people's thoughts. This dream may reflect your deep concern about driving too fast and unsafe.
