"The clock says three. But there's light outside? What the fuck is going on with the clock? Am I late for work or can I sleep a little longer?"

-me at 3 PM on a Sunday after waking up from a post-lunch nap

I once woke up from a nap that overtook me and it was twilight and I didn't know if it was ten on a summer evening or seven in the morning in the middle of winter.

You need a power nap to feel that way?

Hell, that describes my last 30 years of existence.
