What is the principle of Duke Zhou? Is there any basis?

Duke of Zhou was written by later generations in the name of Duke of Zhou Ji Dan, and it was a series of interpretations made by the ancients according to their own understanding of dreams. In ancient times, it was an authoritative interpretation of dreams, but in modern times, duke of zhou can't or can't explain it correctly. Because there are many things that didn't exist in ancient times, such as computers and airplanes.
