Okay, my turn!

Roughly a decade ago, I was working midnights with two other people who were my partners. Anyway, we decided to go explore this tunnel system underneath a school. The lights were on and all, but we had to pull on the edge of the chain link door to get inside. So we're walking, crawling over piles of furniture parts, etc. when we arrive at an intersection. Immediately to our right, there's a cell-like room with a bunk bed, a chair, and some miscellaneous items and it all looks old and abandoned. The place used to be a bunker in case a war broke out, so we weren't the least bit surprised. Was it creepy though? You betcha! So the three of us are standing there, not going inside the cell but peeking in from the hall, when I suddenly hear what I believe was a moan or something from right in front of me. The three of us simultaneously freak out as come to find out, we'd heard the exact same thing but there was no one else there. We ran back as if our lives depended on it. What a night!
