I do. Although, I don't think my house is haunted (even though it's over 100 years old and a woman died here... In MY room, no less), but strange things do happen every now and again. Closet doors randomly open in various rooms.
However, one memory that still kind of creeps me out when I think about it happened when I was around 6 or 7. I was up late at night because something (probably some Goosebumps book cover I saw [not kidding]) scared me. I finally sort of got over it a little and closed my eyes. I was drifting slowly off to sleep. Suddenly, I could've SWORN I felt something kiss my cheek. My eyes opened immediately, and I saw nothing.
