Dream Journal: books bleeding into my sleep

I stayed up a little past my bedtime last night to finish the last chapter of Jo Walton's Farthing, an alternate-history mystery set in a post-WWII Britain in a time-line where the US had stayed isolationist, Hitler ruled the continent, and the UK had made peace with Nazi Germany. I guess the story hit me a little hard because my dreams took me into that setting (at least vaguely) and I found myself having to pack secretly to leave the country and become a refugee because I was about to become the target of politically-motivated violence. But I had to conceal my plans from everyone around me -- they had to think everything was going along normally. The worst part of the dream was that I couldn't take my cat and couldn't leave her behind either, so part of the preparations involved putting her down. But then there was a delay in my leaving and I had to find some way to conceal the body (or mis-direct people about how she died), all the while being terrified that "they" were going to come get me before I could get away.

Definitely not one of my "stock themes" dreams. But clearly set in motion by the novel, so I'm not too worried about it having deeper meanings (other than me still being a bit tense and depressed).

ETA: I should mention that I found the book very well written: engaging protagonists, well-crafted mystery, good use of atmosphere. Just a really really creepy setting.
