" We had been sitting in this crouching manner for some time, when all at once I thought I would open my eyes; for when between sheets, whether by day or by night, and whether asleep or awake, I have a way of always keeping my eyes shut, in order the more to concentrate the snugness of being in bed. Because no man can ever feel his own identity aright except his eyes be closed; as if, darkness were indeed the proper element of our essences, though light be more congenial to our clayey part. "

― Herman Melville , Moby-Dick or, the Whale
