My house is haunted. I have little experiences almost daily. So does my wife, but she doesn't believe in ghosts so she brushes it all off as something else.
See, we're the second owner of this house, the first owner bought it new back in 1951 and lived in it ever since. The old man died in his bed 3 years ago, and the old lady wanted to move, and sold the house to us. The old man was very strict, and very religious, and it was always my assumption that I really piss him off with my brewing beer, viking metal music, etc. And that's how I explain a lot of the weird experiences.
On tuesday night, I come home from work and there were all my mugs in the kitchen, arranged in a circle in the middle of the floor. I normally keep them in a drawer. Stuff like that happens all the time.
