I was taken into the emergency hospital and they were told that I was unconscious for over 5 minutes minimum. I would have thought in such a case that they would have at least kept me overnight and taken some blood tests to look for damage. Apparently all they did was patch up the scraps and scratches and sent me home - in this case the "me" wasn't there. I was essentially sleep walking with no memory and got into all sorts of legal troubles over the next six months until my brother took me to a real doctor who prescribed some medications and I awoke "me" again the next morning.
Now I have medical and legal problems up the ying-yang. I even got a drunk driving charge that has threatened my driving privileges and will multiply my insurance costs.
