Sleep lingers all our lifetime about our eyes, as night hovers all day in the boughs of the fir-tree. – Ralph Waldo Emerson
There is a drowsy state, between sleeping and waking, when you dream more in five minutes with your eyes half open, and yourself half conscious of everything that is passing around you, than you would in five nights with your eyes fast closed and your senses wrapt in perfect unconsciousness. – Charles Dickens
