I saw a ghost, got up in the middle of the night to take a piss and there he was sitting down on the edge of my tub just watching me do my business.
I was kinda shocked, then he asked if I needed a hand, so I kinda ran away. The ghost later got arrested, apparently he likes watching people urinate.. cops told me it wasn't a ghost but I know what I saw!
In all seriousness though, no I havn't, but I want to. We have a ghost in our house, I believe, we got one of those lights that you touch and the brightness goes up every time you touch it. Only at night, it will sometimes go by itself, switching the three light levels over and over, it's pretty creepy.
Or maybe it's just broken...
