On my first night as a security guard at a haunted house, I saw a girl skipping rope in the corridor on the surveillance camera.
When the count reached "99," she suddenly turned her head and stared at the camera. The next day, the old security guard warned me that I had to turn my back to the monitor screen during the night shift.
I did as I was told, but I heard the sound of skipping rope coming from behind, and the girl's chuckle: "100."
What's even more terrifying is that the old security guard died in this building three years ago.
