Nightdreaming
Our species sleeps for the majority of every cycle, leaving us a few “hours” (your term) of awakeness; I’m not sure why you would do it any other way. Those few hours are intense, filled with what sustains our sleep and our society: hunting, eating, mating, manufacturing…tasks that keep us safe while we’re unawake. Because sleep is the part we live for—you should see our dreams. Of beauty, of travel, of exploration, of invention, of fantasy, of creation, of wonder. I pity those who can't sleep for nearly every hour of every day; they're missing out on so much imagining.
