Ugly Sleep

What does ugly sleep mean?

Deep sleep

Ugly sleep is a term that refers to a person's deepest period of sleep. The person is typically so deep into a dream that his body moves into different positions and drool starts to dribble out of his mouth.

The ugly part comes from how a person looks when he or she is in the deep sleep and difficult to wake up. The sleeper's body is sometimes contorted and she is snoring.
