My name is Lin Xiaoyu, a high school student who can play back his dreams repeatedly as a high-definition movie. It wasn't until I pointed to the ancient tree in Wushan that I had never seen before and said "engraved with the word "morning"" that I realized something was wrong. What's even more wrong is that voice that always tells me "Don't look back" in the red and black nightmares - it scared me to the point of breaking out in cold sweat at first, but now, when I roll over in the middle of the night, I unconsciously nod to the fog and continue to sleep.
