Echo Trap

There is an abandoned "Echo Archive" on the edge of the city. It originally maintained files for missing persons, but it suddenly ceased operations many years ago. Until recently, strange events began to occur near the archives: Whenever someone approaches certain "numbered doors", they will hear sounds related to their childhood, and even see images consistent with their own memories. What's even more frightening is that in the reports received by the police station, almost every victim said the same thing: "This isn't my first time here."
