I tend to read fiction with purpose in mind. For example, Ender's Game for ethics, DUNE for ideas about what it means to be human, or Contact for a Pythagorean understanding of the nature of God. My girlfriend thinks I'm weird, but it does make some sense.
One suggestion, read fiction with the purpose of programming your dreams. Books often activate in dreams, since dreams are a way of moving information from short-term to long-term storage. You can view the process as it happens, and have a lot more fun than simply converting text into inner sound, and inner sound into meaning at the rate of 7 +/2 ideas at a time.
