I need my sleep. I need about eight hours a day, and about ten at night.

I am something of a crank about sleep, for if I get seven and a quarter hours instead of eight I feel afflicted and drag myself around, although there's nothing really wrong with me. It's just another idea. That's how it is with my ideas; they seem to get strong while I weaken.

Last night I didn’t sleep for a solid eight hours. No, it melted a little. Damn global warming.

How come you don't work fourteen hours a day? Your great-great-grandparents did. How come you only work the eight-hour day? Four guys got hanged fighting for the eight-hour day for you.

Oh, the terrible struggle that I have had against sleep so often of late; the pain of the sleeplessness, or the pain of the fear of sleep, and with such unknown horror as it has for me! How blessed are some people, whose lives have no fears, no dreads; to whom sleep is a blessing that comes nightly, and brings nothing but sweet dreams.

Methought I heard a voice cry, Sleep no more!
Macbeth does murder sleep, - the innocent sleep;
Sleep that knits up the ravell'd sleave of care,
The death of each day's life, sore labour's bath,
Balm of hurt minds, great nature's second course,
Chief nourisher in life's feast.

If we could sleep twenty-four hours a day, we would soon return to the primordial slime, the beatitude of that perfect torpor before Genesis-the dream of every consciousness sick of itself.

Eight hours of work, eight hours of play, eight hours of sleep - eight hours a day! (From the Haymarket era eight-hour campaign)

People who sleep less than seven hours a night are more likely to suffer from cardiovascular disease, heart attack, stroke, asthma, arthritis, depression, and diabetes and are almost eight times more likely to be overweight.

There are some nights when
sleep plays coy,
aloof and disdainful.
And all the wiles
that I employ to win
its service to my side
are useless as wounded pride,
and much more painful.

Slept, awoke, slept, awoke, miserable life.

Life is something that happens when you can't get to sleep.

We live our lives, do whatever we do, and then we sleep. It’s as simple and ordinary as that. A few jump out windows, or drown themselves, or take pills; more die by accident; and most of us are slowly devoured by some disease, or, if we’re very fortunate, by time itself. There’s just this for consolation: an hour here or there when our lives seem, against all odds and expectations, to burst open and give us everything we’ve ever imagined, though everyone but children (and perhaps even they) know these hours will inevitably be followed by others, far darker and more difficult.

Sleep is where we touch what is better left unexamined. There, the whole of life is bundled up, dwindled. There the carefully hoarded and enjoyed personality, our only treasure and at the same time our only defense must die into the ultimate truth of things, the black lightning that splits and destroys all, the positive, unquestionable nothingness.
