The Interpretation of Dreams

It's comments on the likely causes of dreams have stuck with me for 20 years

Fascinating. I never know what to make of Freud, monumental genius or self-deceiving doofus. Interesting discussion of his children's dreams, including his later to be famous daughter. Interesting review of previous 19th century work on dreams in the first chapter. Basically, he describes the dream, then he states that it seems meaningless without analysis. Then he gives the analysis. Reminds me of one of my favorite quotes: "Thus we can see that these authors had worked out their conclusions far better than their arguments."
