I Am An Early Riser

You know those big green and white signs on motorways? Well I was running towards one when the words on it began shimmering as though fog was over it, or looking through steam, only there was no fog or steam. Then it cleared up. Just after that, I crossed through a football field. Almost in the middle a small stick hit me on the back of my right shoulder. I was in the middle and nobody else was there. and I don't think a bird dropped it because I looked all about and couldn't see a bird. So I think it was a ghost. The stick was only little and couldn't possibly have hurt me.
