No, although not long after my grandpa died I was driving along this old narrow country road in the pouring rain and I was really scared. I was praying that I'd get home safe and at the same his silhouette appeared in windshield, I dunno but it was really comforting. It was like he was looking over me until I got home safe.
I believe in religious supernatural entities like God, spirits, angels, demons, etc., but not in mythical supernatural creatures like vampires, werewolves, fairies, unicorns, etc.
