There is a taxonomy of naps. You'd think the subtyping relies on measuring quality of refreshment, but I don't think so. The 20 minute nap, the deeper 60 minute nap, and then the utterly useless 2-hour, face-down, sweaty two hour nap after which you think you might still need to sleep, and when you wake up, the sheet creases on your face look like scarification. Obviously, that nap was too heavy.

I had this vision: diving into a lake, and arching perfectly so you head to a perfect depth at which you weigh nothing and your motion is effortless. The return to the surface feels pre-ordained.

Now that's the platonic nap.

And, if the water might be words, it's the platonic chapter.
