Around a year ago, I was getting back from a night showing of a movie. Upon arrival at the, I went to the back to grab my things from the trunk, and I saw a shadow in the shape of a dog. Normally, when I see a shadow, its an illusion. A trick. But this thing didn't dissipate, it seemed solid, and moving, ready to attack me. I froze, and couldn't speak for an hour afterward. Is this a sign of some sort? Also, is this the right category for such a thread?
