Just as you are not letting the sperm out of your body, they get out this way, it is called nightfall. As millions of sperms are made daily , then the old one must get out. The two ways are nightfall and intercourse.
Lot of people have that. Its called wet dream
You dream because your brain is thinking while sleeping. Why do you see it? Because it's your imagination. Your imagination gets better while sleeping.

Sperm/ more likely Semen (there is a difference) cannot leak from the bladder, you may be having a wet dream, which is not harmful and perfectly normal.
Sleeping or not, there is still sperm in his ejaculate so yes.

It dies pretty quickly once in the open !
Of course, if the sperm at all gets into the vagina then there is a high chance that the female will get pregnant.
I'm assuming you're concerned about the sperm getting inside your vagina while sleeping or moving in bed. the chances of pregnancy this way is beyond unlikely, sperm cannot survive in that environment for very long, and even if they could they cannot get far enough into the vagina to fertilize your egg. Simply wipe up the semen with a tissue then once over with a damp cloth/tissue and you shouldn't have to worry about it.
