Yes, Duke Zhou.
Dreaming means that after falling asleep, the cerebral cortex is not completely suppressed, and various fantasy scenes appear in my mind. It is a normal physiological phenomenon of human beings, a metaphor of fantasy and a daydream. Description can't be inconsistent with reality. For example, "those who keep the world peaceful from now on are dreaming." Reality is an eternal world of struggle. I hope my answer is helpful to you.
