12. There were decapitated animals everywhere
“Explored an abandoned factory? I think I’m not sure what it was. Extremely sketchy. In the middle of the floor there was a square cutout and just a dark room below it with no light source, around a 8-10 foot drop. Would have been fucked if someone fell down. Also many children toys and random musty books. Tons of bat and pigeon shit and it went up about 4-5 stories. Stairs were very sketchy. Worst part about it was the decapitated animals there but oh well.” — shifting27
13. It always felt like someone was standing behind me
“Many years ago I worked as a technical assistant at a coal mining company. this was basically doing the grunt work for those with degrees, taking samples of things, doing data entry, driving the surveyors around etc etc.
One of my duties was to go into the underground mines and take coal, dirt, and air samples on a regular basis. Often this’d be a little away from other workers.
One place i’d hate going because every time it’d feel and sound like there was someone standing just behind me to my left and whispering in my ear, even when the nearest other person was 30 yards away or so.” — renegade_donut
14. The stairs disappeared into water
“There used to be an old abandoned school in a town by my house. It was heavily boarded up, and super hard to get into. Well, a friend and I managed to get inside, by climbing up the side of the school via a pipe/fire escape combo and slipping through a window on the roof. We explored the basement, which was flooded. It was kinda creepy seeing stairs disappear into water. We had just left the gym, when we heard footsteps coming from the doors on the other side of the gym. Scary, especially considering it sounded like it was one person (not another group of explorers like us) and blocking our exit back up to the roof (the only way out otherwise was behind us, through boarded up doors). They sounded like someone who was walking around, and stopping periodically. There was no light coming from that direction, and we couldn’t fathom why someone would come into a creepy place like this alone. We waited for the footsteps to stop, then snuck across the gym, peered down the hallways, saw no one, and continued towards the stairs which would lead us back to the roof. Halfway down the hall, we hear someone SPRINTING behind us. Probably 50 meters away or so, down a typical high school hallway. Now, it is mostly dark in here, but there was a small amount of light coming in through cracks in the window boards. Still, we didn’t see anything behind us as we quickly ran up the stairs. We didn’t stop until we got back to the fourth floor. We listened for noise; nothing. Hopped out the window and climbed back down the pipe.” — shreditorOG
