The closest I've gotten to a haunted house was an extremely weird night in an AirBnB that said it was a converted girls' school, but turned out to actually have been the women's dormitory of the Idaho State Industrial School, which was a reform school for wayward youth. We did not see or hear anything supernatural - it just struck us as an odd place. Oh, and I wasn't alone, so haunted or not, it wouldn't count. There aren't many houses I have slept alone in, come to that. A couple of places where I was housesitting, and occasionally in our house when everyone else was away.
