Supposedly a ghost lives in my house. My Sister swears she saw it and brought up details (that she didn't know about) that jived with the original story (which will make the hair on the back of your head stand up). Anyway, six months later she stayed over again and I asked her "did you see the ghost?" And she replied "she left".
Short answer "no, I have never seen a ghost".
Have you ever gotten really drunk in order to sleep with someone?
