Worst way I've woken up...
I remember one time, when my bloodsugar dropped too low (I'm diabetic), so I get up to have something to eat in the kitchen downstairs. I make it halfway across my own room when I feel my left knee give out, and I manage to get out a single cry for mom before everything goes black.
Next thing I know, I'm laying on my back, with a glass of jam/milk being poured down my throat, with my mom, dad, and two paramedics I've never seen before hovering over me like a bunch of unholy spirits, and my body aching all over, 'cept for the back of my head, which has gone completely numb since I landed on it when I took a dive into the carpet.
"Fun, fun, fun!" as Yatzhee would have put it.
