Early to bed and early to rise, makes a man healthy, wealthy, and wise.

A nap, my friend, is a brief period of sleep which overtakes superannuated persons when they endeavor to entertain unwelcome visitors or to listen to scientific lectures.

I divide my time as follows: half the time I sleep, the other half I dream. I never dream when I sleep, for that would be a pity, for sleeping is the highest accomplishment of genius.

He who sleeps half a day has won half a life.

The city sleeps and the country sleeps, the living sleep for their time, the dead sleep for their time, the old husband sleeps by his wife and the young husband sleeps by his wife; and these tend inward to me, and I tend outward to them, and such as it is to be of these more or less I am, and of these one and all I weave the song of myself.

Sleep, that deplorable curtailment of the joy of life.

Sleep hath its own world, and a wide realm of wild reality. And dreams in their development have breath, and tears, and tortures, and the touch of joy.

And if tonight my soul may find her peace in sleep, and sink in good oblivion, and in the morning wake like a new-opened flower then I have been dipped again in God, and new-created.

The repose of sleep refreshes only the body. It rarely sets the soul at rest. The repose of the night does not belong to us. It is not the possession of our being. Sleep opens within us an inn for phantoms. In the morning we must sweep out the shadows.

Six hours for a man, seven for a woman, and eight for a fool.
