How do I know if I got enough sleep?

What counts as quality sleep?
Quality sleep means spending sufficient time in each sleep stage, especially deep sleep and REM sleep. Indicators include falling asleep within 20 minutes, sleeping through the night with minimal awakenings, and feeling refreshed upon waking.
