There's a significant amount of people who don't actually get scared of "spooky old houses". Just like there's some people who don't get nervous when a giant spider is on their hand. Or when they're talking to a crowd. Or when they're on top of a cliff.
I'd certainly be nervous in a "spooky old house" but certainly not for its ghosts. I do despise spiders for one thing.
but at the same time, what is interesting to me, is that most of us can get scared by horror films or movies about ghosts. so if you get scared by a ghost in a movie, could that mean you believe, at least for a moment, in ghosts? or would it simply mean that IF ghosts existed, you would be afraid of them.
No, the unexplained lights in the hall at night were nothing in comparison.
