What windowsvo said is almost right. You won't give him extra points, will you?
Explain it a little. I read a little about Freud's interpretation of dreams.
Dreams are the fulfillment of wishes. Dreaming often means what you want to do and what you want to achieve. You pluck your hair, which means you may want to do something bad that windowsvo said.
However, there is an audit system for dreaming. After all, I dare not go too far. The consciousness of dreaming will often pass its own moral examination in disguise and then show it, or change the ending. It says it's from God, which means you want to do bad things in your heart, but you're afraid of being caught.
