In most adults, both saliva production and swallowing slow during sleep.Some medications increase saliva production. The sleep posture can also contribute. When you lie on your back, saliva pools in the back of the throat and often causes a swallowing reflex that prevents drooling.You're also more likely to drool if you breathe through your mouth instead of your nose.

Because they lay on their side and have their mouth slightly open. There's no way they drool when they lay on their back, right?
