well i dunno if it was a ghost,but in my old pad we had a closet in the living room.and once in a while,when me and my ol lady were watching t.v.,sumthing would start knocking on the closet door from the inside.my lady would freak out.so then i'd have to go check what the fuck it was,all fukin scared of course,but i never found anything.this happened about 4 or 5 times.anyway.when we first moved in,the garage was full of satanic,666 type shit painted on the walls.i dunno if that had anything to do with that shit.
