I believe in spirits, not ghosts. I have heard stories and know people with spirits in their homes. I have never seen/heard/experienced myself, but I think it's my faith protecting me from their presence.
We live in a material and supernatural world. Their are too many stories for them not to exist. I believe spirits are dead people, angels, and demons.
I think some people can experience them and others can't.
