No matter how weird science fiction gets (and it can get pretty weird), it still always feels like a pale reflection of the incessant nuttiness of the real world.
Maybe I'm looking for a mushroom-and-fusion-fueled Burning Man spaceship that crashes into itself, tossing out stars like confetti.
Barring piloting that actual machine, the books below are a good way to push your brain in new directions. Some you'll like, and some you'll just detest.
You can get away with almost anything in science fiction. Many writers have tried to do exactly that, and a fair number of them went completely off the rails. Fortunately, a number of hardy, warped souls were able to put together conspicuously strange tales that are still readable, from Meiville's magic to Dick's drug-fueled insanity.
