I'm a weird sleeper, because it's really difficult for me to get asleep, with the slightest bit of light or noise making it impossible for me drift off. However, once I'm asleep, I'm asleep. My body clock wakes me up around the time I need to wake up, but I'd sleep through an alarm, I know I would. Sometimes I wish I could retire into a Poké Ball for the night though, because that way the solitude would mean I wouldn't have to worry about other people snoring and stopping me getting to sleep (I hate snoring with such tremendous passion, it's horrible).
