I have actually. There is a place in tullahoma tennesse named south jackson. I used to a civil war hospital back in the day, now it is an arts centre. Let me tell you, at night time the place is creepy. in the auditorium, on the balcony, there is a seat that will mysterious come down without any one meddling. If you sit in it, another will go down nearby, as a chill runs up your spine. Shit you not, i witnessed it. Door were slammed with no-one there, and we had some crazy things come up on our ghost radar. Yes, ghost radar. Its an app for smartphones. Now, if you're anything like me, you don't believe it. Thats a stupid idea how could that possibly work. We eventually walked into a dark room, and then the ghost radar says (It apparently picks up low frequency sound waves) coat. We look over in the corner, and sure enough, there is a coatrack with a single coat on it, and in the pocket there is a namecard. An old one. Later we went upstairs. on attempt to open a door, there was a force pushing us back, and the radar said "Dick". Are you kidding me? That ghost just called us dicks. Later we go in a room, and the radar says tree. In the corner of the room, there is a christmas tree. It then says flag ground, and at our feet, sure enough, is an american flag. It sounds farfetchd, but this all really happened. Later we had described to us by single words, a murder. The ghost said it was an accident. We looked up records, and once again, we were surprised to find a man murdered there by the same name the ghost supplied us with. A harrowing experience, to say the least.
