Fog Addiction Dream: Small Town Puzzle

My name is Qu Shaohua, and I am being hunted by my own dreams. After arriving in this isolated town, I realized that dreams can also be contagious. The price of infection is disappearance. The only one who believed in me was local archivist Pan Xiaohua. She said that we were uncovering secrets that a small town would rather devour itself to keep. The mayor is watching us. Every file may be a trap, and every dream may be the entrance to disappearance. Now, the only way for Xiaohua and I to survive is to walk into the deepest nightmare and find the evil that originated from it. Because those who know the truth have either become an accomplice, or... Have become part of the dream.
