On the topic of sleeping, I've always wondered what happens when you come across a sleeping enemy. I'd imagine it's majorly frowned upon to shoot a guy in his sleeping bag. Do you wake him up and mercy him? I've never played a 24-hour game, and I haven't read a whole lot of 24-hour game threads either, which would probably mention this in the rules...
Also, when you sleep with your goggles, are there any precautions in case they slip off?
