Non-clinical Sleep and Wake-up Uses

Famous quotes containing the word sleep:
“In a dream, in a vision of the night, when deep sleep falls on mortals, while they slumber on their beds, then he opens their ears, and terrifies them with warnings, that he may turn them aside from their deeds, and keep them from pride, to spare their souls from the Pit, their lives from traversing the River.”
—Bible: Hebrew, Job 33:15 -18.
