Lin Song likes to sleep. He used to dream from time to time. Lin Song's dreams felt very real. He experienced the dream world from a first-person perspective. The world in each dream might be ancient or modern, or a very strange world. I don't know when he started. Lin Song discovered that the dream world was connected to the real world. Even his previous dreams became true, but they were not exactly the same as the dream world. He was not sure which day his dream would become a reality. He began to be afraid of sleeping and dreaming, so he simply stayed awake, but he couldn't stay awake all the time. What should he do?
Concept: The dream world is both virtual and real. Does the dream affect reality, or does reality change the dream?
