I had one too, not that different in spirit.

It was like the Three Billy-Goats Gruff. People were walking across a bridge one at a time, and various-sized monsters were either gobbling them up if the people were smaller, or getting knocked off the bridge themnselves if the monsters were smaller; you never knew which would be next.

The media kept a running count for several days, and I saved all the newspapers. Finally my wife asked me what the pile was, and I had to tell her "These are the Times that size mens' trolls."
