I don't have specific memory of this incident at all, but my friend and I were ruff housing a bit on the third story balcony of his apartment. We both flipped over the railing, I landed on my side breaking most of my ribs, fracturing my spine, punctured both lungs. This all happened on my birthday, believe it or not! I then I fell into a coma for seven weeks. And yes I am a TBI patient as well. (guess you probably figured that much, huh?
