Just Finished:
The Interpretation of Dreams (1899), by Sigmund Freud, translated by J. A. Underwood
In some respects I feel like this is the most difficult book I've read in the last year or two. Sometimes it's a real page turner (insofar as such a book can be) otherwise it's a bewildering rabbit hole for long, numb stretches--fascinating at first, but eventually tiresome. Still, it's a rewarding read, if you have the time and patience for it--both are necessary more than I imagined. And of course, I should stipulate that it's a rewarding read if you've an established interest in its subject--I'm not about to recommend it to everyone.
I think Alison Bechdel's Are You My Mother? is next up for me. My understanding is that the text revolves around dream interpretation and psychoanalysis, so it ought to make for a sensible follow-up to Freud.
