My Dream Connects the Whole Universe

[Hard science fiction + absolute originality + brand new system + interstellar + suspense + scientific reasoning + ultimate imagination] Humanity, an intelligent civilization trapped in a corner of the universe. Their bodies are weak, their technology is low, and they may not even be able to leave the solar system throughout their lives. Hermen, a mysterious race in the universe. They are nearly immortal, travel across the galaxy as observers, and play the roles of saviors, destroyers and bystanders on countless intelligent planets throughout the universe. But if I tell you - Hermen is a human being. Would you believe it? Have you ever seen those bizarre scenes in your dreams? "Marine life" living in a liquid glass ocean; "land plants" that connect planets and satellites and are 10,000 meters long; "fallen civilization" that sinks the entire race into a virtual world... Why do these things that have nothing to do with your life appear in your mind? That is not an illusion, everything is your real experience. During the day, you, as a human being, live on earth and are an ordinary member of society. At night, you transform into Hemen, traveling through countless stars in the universe, absorbing vast information. Who are you? Who am I? Are you and me real? I don't know the answer to this question. But we are all searching. Human beings are just the shell we use to deceive Him. And Hermen will carry all the knowledge in the universe to reach the ultimate - reality. My name is Zhen Shi, and I have been pursuing the truth. Even though... I'm not real.
