"I think what happened in the dream is real." A stared at the person in front of him, "Really, don't believe it."
"I believe it." B nodded and smiled, "Then what?"
"No, you don't believe me. You think I'm joking, but I'm serious!" A stared at B, "Maybe I'm in a dream now. After I go to bed at night, I return to reality."
"Then am I also fake?"
"I can't figure it out!" A lowered his head, very frustrated, "Besides, I killed someone in my dream."
"It's just a dream, don't think too much about it."
Purpose: abide by laws and regulations
