Everyone has bad dreams sometimes and bad dreams are no fun. But still, I just wanted to ask, what is the scariest dream you've ever had? The scariest dream I've ever had was when I dreamed it was midnight and it was a full moon, I looked out the window and saw the scariest thing ever! I saw a guy that had yellow eyes and he had a horn on his head. The guys skin was red and I mean it was literally red like the color red. He looked like a demon and he kept staring at me and he grinned and showed his teeth which were like sharp fangs.
