I reread Flow My Tears, the Policeman Said, a Philip K. Dick book that I read in high school and remembered nothing about, other than that I didn't get the ending.
On this read, I realized how efficient a writer PKD is and how he's actually pretty funny. But very male-gazey as well. (Though maybe that's the main character's skew?) Also, the future 1988 that he wrote about in 1974 has both video phones with color matching games on them and flying cars.
I also did not know what to think of the ending this time. It's BS from a plausibility perspective. But was it worth doing to get the reader to think about the nature of reality? Because I can't deny that I enjoyed thinking about what was real to whom throughout the book.
