I live in an old house that's supposed to be extremely haunted. There's a ghost story for every room in the house and everybody in town thinks it's haunted - so much so that I get people telling me stories about my own house at parties (even when the person has never been in my house), and always respond something like "Oh, yeah, the walls drip blood at midnight" or whatever. I've lived here for 15 years and never experienced anything out of the ordinary.

Seems like there are people that experience ghosts (or whatever) and those that do not. I suffer from sleep paralysis and have experienced some pretty freaky things, but it's all in line with typical sleep paralysis experiences - previous owner of my house even left me some typed out "ghost stories" that were obviously her experiences with sleep paralysis. Personally I think sleep paralysis and pareidolia account for the vast majority of ghost and abduction stories, with the effects of environmental infrasound throwing in a wild card here and there.

Still enjoying this thread. Still live in a "haunted" house. Still don't believe in ghosts, but want to

During the couple years between my first post and now, I built an infrasound cannon, and a friend helped me construct a variable frequency sine wave device that can run continuously through it (you can also use modulators on your phone). The idea is that prolonged exposure to subsonic sound (particularly 18.9 hz, the "ghost frequency" which supposedly causes your eyeballs to vibrate thus causing hallucinations and even lower frequencies, say those of 6-9 hz that cause bodily organs to vibrate, inducing feelings of distress or anxiety similar to the mythical brown note) can make you see and feel all sorts of things.

So far it has not made me see a ghost, but can confirm it's not something you want to be around for a long time. If you have annoying neighbors, it's potentially great though.
