Perhaps because of Ren Shui's fate, he has been haunted by nightmares since he was a child. He remembers clearly what happened in his dreams when he woke up. He didn't have the habit of recording dreams when he was a child. When he was in high school, he started posting supernatural events or nightmares to his friends circle. The response was quite good, and he asked for updates. After thinking about it, I might as well write down these fragmentary stories, and maybe I can find the connection between them.
Concept: Nightmares are like the breath in your ears while sleeping
