Do Androids Dream of Electric Sheep?
Well, I say 'reading'. I've been nursing the book for 4 days and I'm 5 pages in. Somehow don't have the concentration for reading anymore, even though I used to read a LOT years ago. ¬¬ Do you ever get when you've read a whole paragraph and realise you didn't take in a single word of it? It's like that. Except you read the paragraph again and it still doesn't sink in. How useful.
Is this
literally your first book after a long reading hiatus? If so, your concentration may have atrophied. Keep working that muscle, it'll come back!
That said, I've read a few of Dick's works and he's certainly hit-or-miss as far as presenting a lucid writing style. It's been well over a decade since I read DADOES so I don't specifically remember its level of "difficulty." I do remember UBIK (having read it last year), and it was on the easier end of his spectrum. In contrast I remember greatly struggling with VALIS many years ago.
The same swings in style can be seen in the excellent collection of non-fiction "The Shifting Realities of Philip K. Dick". He was a man with troubled and difficult thoughts who often struggled to express them. Don't blame yourself!
That said, I'm currently reading "Behold the Man" by Michael Moorcock. It's a time-travelling, mildly hallucinogenic take on the Christ parable. Dick would have liked it. Although its style is only tangentially similiar to his, it utilizes sci-fi in a similar manner.
And some comic books. :\
