When I was little, I never wanted to say the Holy Ghost part from "in the name of the Father, the Son, and the Holy Ghost" when I said my prayers. This was because I was afraid of ghosts (the kind that wore sheets and haunted people) and I believed that if I mentioned that word in a prayer, a ghost would overhear and appear in front of me, thinking I had called it. So instead I always said "Holy Spirit," because I thought that spirits were the friendly counterparts of scary ghosts, and I didn't think I'd mind if I accidentally called one of them.
