I want to sleep with you, fall asleep and sleep. That magnificent folk word, how deep, how true, how unequivocal, how exactly what it says. Just – sleep. And nothing more. No, another thing: and know right into the deepest sleep that it is you. And more: how your heart sounds. And – kiss your heart.

- Marina Tsvetaeva, Letters, Summer 1926

When your day has been teeming with different sensations, when you have things on your mind, you can get to sleep to start with but you can't get back to sleep. Sleep comes a lot more easily than it comes back.

- Victor Hugo, Les Misérables

- Aristotle, On Sleep and Sleeplessness
