Gross!

I was scuba diving not too long ago and I was trying to equalize the pressure in my head as I was descending into the inky darkness of the abyss. I plugged my nose and blew into it too hard and I burst a blood vessel in my sinuses. My mask began filling with blood and my ears bled, too. As I surfaced, the decreasing pressure caused the blood to spurt out of my ears underwater.

When I surfaced, all I could taste was blood. The blood eventually coagulated in my head and I was coughing and sneezing chunks of mucus coated jellyfied blood.
