No, Not the Casper type ghost that a lot think of as ghosts.
But I have seen my mother in spirit, and I have sensed other spirits, also seen thick mists hovering in our last house.
Never felt really threatened by anything, just a bit uncomfortable at the strange feeling when it is a spirit I have not known, my grandmother was one and a friends father was the other.
I also witnessed both my dad and my mother-in-law seeing spirits of loved ones shortly before they passed.
I suppose you have to see it or feel it before you believe in it.
