“As far as dreams were concerned—well dreams are generated by the random processes of neural oscillation during the brain’s rest phases. What dreams do is cycle and recycle images and feelings, rationalisations and fears. There’s nothing special about that. It’s not the dreams that matter (chaff, mental turbulence, the rotating metal bars moving endlessly through the transparent tub of metaphorical slushy). It is what the problem-solving circuits in the mind make of the dreams. Dreams iterate and test mental schemas, discarding the maladaptive to return the adaptive to the slush to be reworked. Dreams are emotional preparations for solving problems—that is why we have evolved them, because problem-solving abilities are highly adaptive and thus strongly evolutionarily selected. Dreams intoxicate the individual out of reliance on common sense and preconception, and tempt her into the orbit of private logic. Dreams have utility.”

Context: A dream! What is a dream? And is not our life a dream? I will say more. Suppose that this paradise will never come to pass (that I understand), yet I shall go on preaching it. And yet how simple it is: in one day, in one hour everything could be arranged at once! The chief thing is to love others like yourself, that's the chief thing, and that's everything; nothing else is wanted — you will find out at once how to arrange it all. And yet it's an old truth which has been told and retold a billion times — but it has not formed part of our lives! The consciousness of life is higher than life, the knowledge of the laws of happiness is higher than happiness — that is what one must contend against. And I shall. If only everyone wants it, it can be arranged at once.

Context: How do I know that enjoying life is not a delusion? How do I know that in hating death we are not like people who got lost in early childhood and do not know the way home? Lady Li was the child of a border guard in Ai. When first captured by the state of Jin, she wept so much her clothes were soaked. But after she entered the palace, shared the king's bed, and dined on the finest meats, she regretted her tears. How do I know that the dead do not regret their previous longing for life? One who dreams of drinking wine may in the morning weep; one who dreams weeping may in the morning go out to hunt. During our dreams we do not know we are dreaming. We may even dream of interpreting a dream. Only on waking do we know it was a dream. Only after the great awakening will we realize that this is the great dream. And yet fools think they are awake, presuming to know that they are rulers or herdsmen. How dense! You and Confucius are both dreaming, and I who say you are a dream am also a dream. Such is my tale. It will probably be called preposterous, but after ten thousand generations there may be a great sage who will be able to explain it, a trivial interval equivalent to the passage from morning to night.
