In college I decided it would be a good idea to sleep on the top bunk of a bunk bed that was in my dorm room that only I lived in (So there was no reason for me to sleep up there as I always slept on the bottom) I was super drunk...brillant idea. I woke up the next morning on the floor in a pool of blood. I must have rolled off the top bunk and I cracked my head open on the corner of a dresser. I had no idea how bad it was until i went to class later and started seeing spots in my vision. I went to the school nurse and she looked at the back of my head (I hadn't seen it) and said go to the ER right away. Ended up hitting my head so hard my brain smacked off my skull. I woke up blind in my right eye the next day b/c they said my optic nerve was bruised. Thank God I fully recovered....didn't learn my lesson though and continue to drink.
