I kinda know how that feels. I got hit in the head by a falling bowling ball but it only fell about 3 feet onto my head.
High enough so that it bounced off my head and then, after I fell face down, it landed on the back of my neck and rolled down my back and legs. Gave me a good scare and a wicked headache.
I was in the bowling center locker room putting my equipment back into my bottom locker and the vibrations caused a ball to roll out of the top locker. The bowler had a couple of balls stacked on top of each other.
