Drooling while you sleep: What you should know about this sleep habit

Some sleep habits are more revealing than people realize. The strange little things you do while asleep — drooling, talking, stealing blankets, curling into a ball, or even grinding your teeth — may reflect hidden parts of your personality, emotional state, and the way your mind handles stress and comfort.

Of course, sleep habits are not scientific personality tests. But psychologists have long observed that the way people sleep can sometimes mirror how they behave emotionally in daily life.
