I was with a construction and demolitions company for a while, and I got a job out in the middle of no where, about 30 minutes of driving about 110mph from the nearest residence or other structure. It was a gigantic abandoned old school or hospital, I couldn't tell, but it was gigantic and had only three or four windows in the entire place. In the basement there was one gigantic circuit breaker housing(it had been updated within the last 10 years) and while we were working, we tripped the entire thing, so we had to go reset it. One of us lost the group(me) and decided to start wandering around trying to find the box again. I beat them there, and just to scare them, I locked the door, went out through another door and started banging on the walls, slamming my tools onto the floor, etc. and eventually I started hearing the others screaming and running away, and after a few minutes, I turned the power back on, and went out the back, and was asking them why they sere so freaked out. The next day, I intentionally tripped the breakers again, and this time I brought a gigantic sledge hammer with me, and I was pounding the cement floor with it, and I heard them screaming again, but this time I only heard one of them run away, and I heard someone getting closer, so I hid up ontop of some boxes in a corner. After a while, they got close to the room I was in, and came in, they started waiving their flashlights around, and I geuss they didn't see me, so after they were infront of me with their backs towards me, I jumped out of the boxes and tackled one of them, and damn did they take off. I continued doing this for the rest of the week, and eventually one of hem figured out that I was never around when this stuff was happening. That was the most fun I've ever had, I wish I had a giant chain as well to get the entire haunted effect. I got fired for slacking off on the job. They were all too embaressed to tell the stroy to anyone else. The building is still standing, the crew abandoned it a day before anyone figured out it was me who was doing it. If you want directions to hte building, IM me.
