John Updike said this quote

“ The mind cannot fall asleep as long as it watches itself. Only when the mind moves unwatched and becomes absorbed in images that tug it as it were to one side does self-consciousness dissolve and sleep with its healing, brilliantly detailed fictions pour in upon the jittery spirit. Falling asleep is a study in trust. Likewise, religion tries to put as ease with the world. Being human cannot be borne alone. We need other presences. We need soft night noises-a mother speaking downstairs. We need the little clicks and sighs of a sustaining otherness. We need the gods. ”
