Though perhaps most famous as a novelist, Philip K. Dick wrote more than 100 short stories over the course of his career, each as mind-bending and genre-defining as his longer works. Philip K. Dick's Electric Dreams collects 10 of the best. In "Autofac," Dick shows us one of the earliest examples (and warnings) in science fiction of self-replicating machines. "Exhibit Piece" and "The Commuter" feature Dick exploring one of his favorite themes: the shifting nature of reality and whether it is even possible to perceive the world as it truly exists.

In Our Friends from Frolix 8, the world is run by an elite few. And what determines whether one is part of the elite isn’t wealth or privilege, but brains.

Is the Glimmung good or evil?

The planet is vast and largely unexplored, populated mostly by gelatinous cube-shaped beings that give cryptic advice in the form of anagrams.
