The lights were back again over the streets. He wonder what they were and what they wanted. All kinds of thoughts were going through his head; aliens, government mind control, a prank?
The lights came in a circle shape, were blue and became hazy if you looked at them too long. They didn’t seem to move much, just hovered at roof level.
He had noticed though that only some people seemed able to see them. Others were left confused at the pointing and whispering.
When the dead started appearing, he knew the meaning of the light circles then.
