If your body wakes you up naturally and you feel refreshed but you only slept 5hrs, have you slept 'enough'?

Whether you slept enough depends only on how much time have you spend in deep sleep. You need only 1,5h(or 2h not sure) of it. So it is possible that after 5h you have it enough. But how you feel after waking up doesn't say as much about whether you slept enough, as about during what part of sleep cycle did you wake up. So its hard to say.
