I work for a Medical Examiner and used to be on the graveyard shift alone. The first night I was on at midnight on the dot our air system shut off which caused the vents to warp. That shit sounded like somebody running through the vents in the ceiling on all fours. Thankfully I got used to it lol but def creepy at first.
Another night we lost power and stupid me watching a horror movie working so hard almost shit my pants when EVERYTHING went dark and knowing that a room with around 30 dead bodies in it was walking distance away. That one I stayed in my car for. Not to mention the constant long dark red lit hallways. Glad I’m not on overnight now.
