When I was younger I went to a summer camp for many years. When I was old enough, I became a counselor. This was going to be so exciting; I was going to be able to keep going to camp, and have so much more freedom. One thing I especially liked to do was go on walks at night once the kids were asleep. Most counselors would go to the staff lounge and waste time on Facebook, but I think a beautiful Berkshire night isn't worth wasting inside. This has become a regular thing where I would set out at 11:00 pm and walk a loop around camp with my phone flashlight. But about 3 weeks into camp something very strange happened. One night I altered my walk a bit since I forgot something in the art building (I was a rocketry counselor). I was still going to do my normal loop so I left my phone in my bunk, thinking I would pick it up after. I headed down to the building and walked in. The lights in the building didn't work after a huge storm so I would just dart in quick, get what I need, then leave. I headed into the supply closet where I left my schedule for tomorrow. The closet was a small room with an old wooden door that always stuck. I peered around in the cramped room looking for the paper, but it wasn't on the shelf where I left it. I checked the floor for the paper and noticed it in the corner. I crouched down to get it when I heard the door slam shut behind me. I wasn't sure whether it was a huge breeze from the lake or someone pulling a prank on me, but I was scared. I tucked the paper in my pocket and slowly moved towards the door. I try to push it open, but no luck. It started raining outside, really hard. Water started pouring in the room from under the door. The room wasn't going to fill up or anything, but it was just very sudden and frightening. I hit against the door, but it wouldn't budge. I realized that I was stuck in there for awhile so I sat down in a chair in the corner and waited. I sat in there for ten minutes and then the rain suddenly stopped. I waited a minute and slowly crept towards the door. I pushed on it and it opened with ease. I dashed out of the building and quickly headed back towards my bunk. I slowly crept in and went straight to my bed. I thought over what happened and wondered how the fūck the door stayed shut like that. After that night, I stopped going on those late night walks and joined everyone else in the staff lounge. TL;DR I got locked in a small pitch black room. Door shut behind me and got stuck. I still have no idea how it happened...
