I do. I never seen one YET but I do. Lolz while I was at Texas for Christmas break, my aunt told me that there is a ghost at her house looking for me! XD I told her "Really???!?! Can't wait to see it." I was do hype xD
In theory, if you believe in ghost then there is a chance you won't see one. If you don't believe in ghost SOMEDAY a ghost will pop up around you... something like that.
Bless your house... That sounds freaking yo... O.o
