Right out of college I got a job as an IT manager for a company that owned a small chain of adult video stores. My job was basically to take care of the Point of Sale system (which was rather complex for a small company of adult video stores), maintain the company website, and do other computer related/data related tasks. Basically I was there to put out fires. About 2 years into the job, the company added 4 additional stores when another company hit financial hardships and was forced to sell off some of their stores. All four of the new stores were in the same state as my company's stores, but in different towns. For 1 month, I and a couple of the other managers from my company spent that time going to each of the stores and setting them up with our company's inventory and equipment. One of the new stores was just outside of a small town in the middle of the state, off of a major highway. The store used to be a small, single story, highway motel that was right next to a large truck stop. When it was converted into an adult video store by the previous company, they walled in the porch that ran the length of the motel, converted the motel office to the video store, and made each of the 20 motel rooms into large video viewing rooms that patrons could rent out to watch movies. The rooms were only accessible via the walled in porch, which was now a long corridor that ran down the building. All the rooms, along with the corridor, were painted black from floor to ceiling. Red tinted lights dotted the ceiling of the corridor at intervals far enough apart to give just little spots of light on the floor of the otherwise pitch black hallway. Each viewing room had just a small light in the center of the room's ceiling. It was by far the creepiest setting I had ever been in. I could only imagine what it was like when the previous company had the viewing rooms active: to walk down that creepy dark hallway with the muffled sounds of sex tape audio and fapping echoing from behind the closed doors.
One night, I was working late finishing up some adjustments on the store's new security cameras. Everyone else went back to the motel we were all staying at, and it was just myself and the night shift guy who we moved from one of our other stores to help out. I had the only set of keys to the back of the store where the hallway and viewing rooms were located as I was using the place now for storage of some of the old equipment left by the previous owners as well as some back stock of merchandise that we had left over from the setup of the store. I was about to move a box of adult novelties that were on the floor to the back area when I passed by the counter and noticed the night shift guy looking around for something. I asked him what was wrong, and he said that he just put his glasses down on the counter not long ago, and now they have disappeared. We had very few customers that evening, so I assumed that they were just misplaced somewhere in the store and that no one had run off with them. I told the night shift guy that I would help him look for them when I got back from storage.
The door to the viewing room's hallway had only one entry door, which locked automatically and had to be opened with a key inside the store. Since I had the only set of keys, I was the only one that evening to go back into the hallway. So, I unlock the door, and proceed to take the box of novelties and find a place for them within one of the vacant rooms. We decided to keep everything in just a few rooms at the far end of the hallway, which meant I had to walk down the creepy hall to the last couple of rooms at the end. As I walked down the hall, I kept turning my head to the right, checking each of the rooms as I passed them. I think I did it because every time I passed the rooms and didn't turn to look into each one, I kept seeing movement out of the corner of my eye in the shadows of the dimly lit viewing rooms. I kept moving, getting more nervous as I past each room, until I got to the room that was in the center of the hallway. I stood there at the doorway, and instantly dropped the box of vibrators I was holding. There, in the middle of the room, lit by the single overhead light, was a pair of glasses.
I stepped into the room and walked to the glasses lying on the floor. I got the oddest feeling as I stood there in the room, as if someone was watching me, from the shadows in the room, just outside the circle of light on the floor from the overhead lamp. I closed my eyes, and picked up the glasses from the floor. I then stepped back towards the door, and ran down the hallway, leaving behind the fallen box on the floor. As I ran down the hall, I did not look into the rooms as I passed them. Once again I could have sworn I saw movement from the shadows of the rooms as I passed them. I exited the hallway through the door to the brightly lit store. I passed by the counter, holding up the glasses to the third shift guy. He asked me where I found them (they were of course his glasses) and I told him they were in one of the back rooms. He looked puzzled and said that he wasn't even back there today. I told him I know, since I was the only one that had been back there that evening and there was no way he could have been back there without the keys. I gave him back the glasses and told him I was going to call it an evening.
I never heard of another creepy incident like that again in the store, but I heard that none of the other employees liked going back into the storage area by themselves.
Tldr: I think the adult video store I worked at was haunted.
