Maybe It's a Novel

I had a dream. In that world, there were four-wheeled carriages, which they all called cars; I had a dream. There were no cars, no mobile phones, and no electricity in that world. I felt like I was going crazy. Just when I was about to go crazy, I suddenly discovered that there might be "immortals" in this world. I tried to integrate into this world. Yes, I began to embark on the path to find immortals... What kind of world is this, and what kind of dream is this? I feel like I am about to wake up, but I haven't found the "immortals" yet.
