I was doing a Facilities Deactivation on an abandoned Insane Asylum in Mich, It was still day time and as i got closer to the medical area It start getting really cold, which was weird because it was an 85 degree day and all power and utilities was shut off to the facility. So I'm doing my work and I see a young lady that looked about 17 or 18 and she just took off running. And I'm thinking shes real so I'm trying to chase her down because abandoned buildings are very dangerous. So i get to the end of the hall which looks like a store area and she Say's "no you caught me again" Like she was scared, just vanished. At this point I'm like scared as **** so I'm leaving out of the store area, and i noticed an old file with all the contents out, and its the girl only shes 19 and turns out she excaped from the Asylum over 5 times, and She died during "Brain" operation to remove the tissue that causes her personality to change. Her name was Sarah Peterson, I still see the image of her frightened face every now and then.
