If you haven't gone all day, then you're using your muscles to avoid going, and thus if you fall asleep, your muscles will relax and you'll go.
While it is possible to pee because of a dream on rare occasions, the vast majority of (adult) people don't -- they wake up when the need gets too great. If this is happening to you often, you may want to see someone about it...

Stopping breathing in your sleep is called Sleep Apnea. If this is happening to you often, you should seriously consider seeing a doctor.

Both of these conditions are real medical issues. I don't think that a game forum is the right place to be discussing these things, much less joking about them. Seriously, if you are regularly having these issues, you should probably talk to someone about them...
