I love fairy tales because of their haunting beauty and magical strangeness. They are set in worlds where anything can happen. Frogs can be kings, a thicket of brambles can hide a castle where a royal court has lain asleep for a hundred years, a boy can outwit a giant, and a girl can break a curse with nothing but her courage and steadfastness.

If you think about evolution, sleep, at some time, was a dangerous undertaking. You lie down in your cave or shelter, and along comes a predator and has you for dinner. Many creatures do not sleep or sleep while standing so they can escape from dangerous situations.
