DXHe's still not responding to us...
I finally got the full story of what exactly happened, and thought I'd share it with you guys.
He was rocking in one of the recliners while watching a movie. (Take note that he was FULLY AWAKE! at the moment!) He fell out of the chair and hit his forehead, without using his arms to catch himself. His head took the brunt of the fall. He screamed and cried for a few moments, rubbing his head, but after those few moments, he just kept rubbing his head in the exact same pattern over and over again, while staring strait ahead. His pupils are almost as big as his eyes and he is just mumbling and muttering, too.
