How to read this
Every quote here was checked against a primary published source, because the internet is full of misattributed dream quotes. Direct quotes keep their original punctuation. Translations name the translator, since the same sentence reads differently in each edition. Where a text survives only as an oral account written down by someone else, as with Black Elk, the attribution says so. Dates for ancient texts are approximate. Popular quotes that did not survive verification are named at the end rather than silently included. If you spot a source we missed, write to [email protected].

Questions people ask about dream quotes
What did Carl Jung say about dreams?
Jung called the dream "a little hidden door in the innermost and most secret recesses of the soul" in Civilization in Transition (Collected Works vol. 10, §304). He read dreams as natural products of the psyche that balance our waking attitudes, and he refused to give dream symbols fixed dictionary meanings.
Who called dreams "the royal road to the unconscious"?
Sigmund Freud, in The Interpretation of Dreams (1900). His full sentence, in James Strachey's translation, reads: "The interpretation of dreams is the royal road to a knowledge of the unconscious activities of the mind." The popular short version trims that sentence down and drops the reference to interpretation.
Which Shakespeare play says "we are such stuff as dreams are made on"?
The Tempest, act IV, scene 1, spoken by Prospero. The line is often misplaced in Hamlet and often misquoted as "made of"; the original reads "made on." Hamlet's own dream line is different: "To sleep, perchance to dream. Ay, there's the rub."
What does "a dream not interpreted is like a letter not read" mean?
It is Rav Hisda's saying in the Talmud, Berakhot 55a. The point is that a dream only does something when you engage with it: left unexamined, it is a message that was delivered but never opened. Jewish tradition treats interpretation as part of the dream itself, not an afterthought.
Did Jung really say "Who looks outside, dreams; who looks inside, awakes"?
Yes. It comes from a letter Jung wrote in German to Fanny Bowditch on 22 October 1916, translated in his published Letters, volume 1. Because it is usually shared without any source, it is sometimes suspected of being a fake quote. This one is real; the sourceless sharing is the problem.
