Weirdness Magnet

I drove by the Clinic today and was stopped at a stop light. I turned to look at a person standing there on the sidewalk by where I was stopped.
The man was very pale, very grey. He looked directly at me. There were dark circles under his eyes and some sort of stain on his shirt. I thought he might be a bum, for a moment. I looked back up at the light, for just an instant, and then back at where he had been, but he was gone. There was nowhere he could have hidden himself in that span of time.
