Naps

What it the technical definition of a nap?

I question this because today was a gloomy day, and when I awoke at nooner and laid there for 30 or so minutes contemplating the daily grind I decided that it would be a good time to take a nap and closed my eyes. 2 hrs later I started my day.

So I guess it could be called "still sleeping", but I was awake for a bit before deciding to close my eyes again.?

I'll just go with it was a nap. That way I won't feel like the worthless lump of a human being that I've lately become.
