Anyone believe in Ghosts ?

When I was 17 (hey sounds like a Sinatra song) we lived in a house that was a converted old folks home. It had 7 bedrooms and five bathrooms and a basement that made your hair stand on end when you went down there. Doors would slam by themselves, we would hear loud crashes up stairs but when we went to see what it was nothing would be wrong. Always had the feeling someone was watching me there. I was really glad to move!
