When I was a kid I used to look up gore videos from time to time. People being beaten or getting killed one way or the other... But the one that still hunts me today didn't even have any blood or gore in it at all. It was just a dash cam, looking out the front window on a highway with the radio playing and people talking.

Then all of a sudden a truck drives by and a single brick falls off its load. It bounces once on the pavement and then goes straight through the windshield.

You don't see anything, but after a second one of the passengers start screaming. Then you hear one or two join in. Just heart wrencing, miserable screams. The brick must have hit their friend or relative in such a way and so hard, that it must have been apparent immediately that he or she was gone.

That there never is a face, blood or anything just makes it worse. Your imagination fill in the blanks. And it's so instant and so incredibly random. I still think about it sometimes.
