The Person in the Mirror Has Been Waiting for Me for Thirty Years

At three o'clock in the morning, I received a private message: "There is someone behind you." When I turned around, there was no one. There was an additional photo on the screen - I was sitting in front of the computer, and in the mirror behind me, there was a figure looking down at me. After calling the police, the police said: The IP address of that account is right next door to your house. But the room next door had been occupied thirty years ago.
