“The sleeping style of each organism is exquisitely
adapted to the ecology of the animal. It is conceivable that animals who are too stupid to be quiet on their own initiative are, during periods of high risk, immobilized by the implacable arm of sleep.”

“What functions do dreams serve today? One view, published in a reputable scientific paper, holds that the function of dreams is to wake us up a little, every now and then, to see if anyone is about to eat us. But dreams occupy such a relatively small part of normal sleep that this explanation does not seem very compelling. Moreover, as we have seen, the evidence points just the other way: today it is the mammalian predators, not the mammalian prey, who characteristically have dream-filled sleep.”

“Much more plausible is the computer-based explanation that dreams are a spillover from the unconscious processing of the day's experience, from the brain's decision on how much of the daily events temporarily stored in a kind of buffer to emplace in long-term memory... The American psychiatrist Ernest Hartmann of Tufts University has provided
anecdotal but reasonably persuasive evidence that people who are engaged in intellectual activities during the day, especially unfamiliar intellectual activities, require more sleep at night, while, by and large, those engaged in mainly repetitive and intellectually unchallenging tasks are able to do with much less sleep.”

“However, in part for reasons of organizational
convenience, modern societies are structured as if all humans had the same sleep requirements; and in many parts of the world there is a satisfying sense of moral rectitude in rising early. The amount of sleep required for buffer dumping would then depend on how much we have both thought and experienced since the last sleep period.”

“This looks very much as if the integration of the day's experience into our memory, the forging of new neural links, is either an easier or a more urgent task. As the night wears on and this function is completed, the more affecting dreams, the more bizarre
material, the fears and lusts and other powerful emotions of the
dream material emerge.”

“There is some evidence that dreaming is necessary. When people or other mammals are deprived of REM sleep (by awakening them as soon as the characteristic REM and EEG dream patterns emerge), the number of initiations of the dream state per night goes up, and, in severe cases, daytime hallucinations-that is, waking dreams-occur.”

“Thus, an inhibition center developed below what in humans is the temporal lobe, to turn off much of the functioning of the reptilian brain; and an activation center evolved in the pons to turn on the R-complex, but harmlessly, during sleep.”

“A fickle lover, sleep takes us as it will, when it wants, and how. Sensing her desperate need, however, it draws Corrie deeply into its embrace, somewhere between her tears and terror.”

“And sometimes when I tilt my head,
in that deep sleep, I realize I forgot to tell you
what happened at work, in the thick of,
all other rubbish daily stuff.
And then I hate to believe, it’s more than
5 hours to hit the snooze, and now suddenly
the night seems longer- than any lazy afternoon.
I want to talk to you now, before I forget
How I have imagined you will react, word by word,
And act by act.
But I kind of manage dozing off in a few minutes,
And I clearly forget it morning,
This entire instance.
But tonight- when you are asleep, and I am
Wide awake like a snake, I don’t say I forgot any
Buzz to discuss, but I have this insane gush
Of words of tell you I how much I have loved you through.
Precisely none of this should be forgotten,
So I decide to write this poem and tell you,
I am so much in my moment of truth.”
“But who, in these modern times, slept well?”
