Was in a hotel. Hadn't slept in a week. Woke up, leaned over to get out of bed. Still asleep, slipped crashed hard into sharp bed table corner. Even asleep, quick reflexes meant I didn't cave my skull in. Instead, I found myself in a ball on the floor, my arm split open , entire forearm blue black and purple, gushing blood. Still have a scar from it 2 years later.
