Have any of you ever seen a ghost/spirit/angel/demon?

Yes! When I was young I saw the angel of my great grandpa. I still remember, but not too well because I was about 6 or 7 years old. It was a few days after his funeral, and I had not really understood what it meant when everyone was saying that he was dead. He was the first person I ever lost. My mom said that she was very sad and just worrying like people do when they lose loved ones. One day we were driving and I saw him in the sky. I pointed and said, "Look! Its Poppy!" My mom was confused, and said, "Oh...". I then went on to tell her that he was really little (I remember him being far up in the sky), dressed in all white, and also said, "He has a huuuge smile!" My mom, who was driving, began to cry, but was finally at peace with losing her grandpa.

One time my friend and I were driving past a graveyard by my house and we both swear that we saw a ghost for a split second...
