Mouth opens: Nocturnal drooling occurs when your mouth cracks open and reflex salivation occurs due to the drying effect of air movement. Maybe occurring intermittently due to nasal congestion I suspect.

Drool : Muscles relax, mouth may hang open, and if you are on your side or stomach, gravity and pooled saliva do the rest.

Mouth-breather: Because you sleep with your mouth open and drool runs out. We produce saliva all night and when a person sleeps with the mouth closed there is a stimulus to swallow the saliva at a certain volume.
