One Soul, Two Bodies: Immortality Is a Curse

When I woke up from my sleep, the painful wounds on my body reminded me that this was a real world. But in my mind, reflections of another world keep popping up, with tall buildings and hurried passers-by, this is another world. I had a splitting headache, fell asleep again, and woke up a second time in my own bed. "That was a dream?" "Why is it so true?" The wounds on my body are gone, but I can accurately call out the name of the place that appeared in the dream world - Mei Ya Hai! A stranger came unexpectedly and I was knocked unconscious. When I woke up again, I was on the red beach again. I collapsed. Which is the real world? Why did they kidnap me?
