I am perfectly refreshed with 5 hours sleep for exactly that reason. I have narcolepsy. Basically I fall asleep immediately and hit REM sleep a minute or two later. That saves the 90 minutes it takes most people need to reach the REM stage. My normal sleeping pattern is in bed at 1am, up before 6am, at work by 7am.
