Interesting! I have the same experience with the one time a group of teens attempted to mug me. I can remember the sneer on the kid's face as he cocked back and readied to punch me, I was holding textbooks under my right arm, standing 3/4 of the way toward the street on a brick sidewalk at a particular intersection in DC.
I guess that the story is already quite explicit as it is: simply recalling all that amount of details is a clear indicator of how much the time slowed down for the gp during the event.
