" He imagined that he was looking for her and couldn't find her anywhere, that the two of them were lost on a vast ship, sleep is a skilled magician, it changes the proportions of things, the distances between them, it separates people and they're lying next to each other, brings them together and they can barely see one another, the woman is sleeping only a few yards away from him and he cannot reach her, yet it's so very easy to go from port to starboard. "

― José Saramago , The Tale of the Unknown Island
