This happens semi-regularly (maybe once or thrice a year?) where I'll wake up due to intense cramping in my calve (generally the left one). Apparently this wouldn't happen if I ate bananas but bananas are disgusting so I guess I get to wake up to intense pain and, what I'm told is a grotesque looking bit of leg-musculature.
I've had a few rude awakenings and this was responsible for several when I was a teenager. Hasn't happened in years which I'm thankful for because the amount of pain when that happens is unbelievable. Pretty much every time I'd wake up as it was coming on, manage to get out of bed and then be on the floor before I made it to the door, usually writhing in pain until it subsided enough for me to massage the area and start trying to walk it off. The worst was when it happened several hours before it was time to get up, so I had to go back to sleep, then start trying to work it out all over again when I woke up.
Aside from that, two others come to mind. In my old room at my parents house I had a ledge running alongside my bed which our cats would occasionally get on to look out the window. Once woke up to one of them jumping off and landing square on my testicles. He just kind of stood there on the bed as I grabbed my junk and curled up in a ball.
Another time was in High School. I had my drum kit in my room, but due to space reasons the ride cymbal was awfully close to my bed. Through what I can only assume was a combination of its stand not being as stable as I thought and me hitting it somehow in my sleep it fell over and hit other stands before finally hitting the floor. There is absolutely nothing like the sound of a 20" ride cymbal falling over to scare the living shit out of anyone sleeping next to it.
