So I have been having REALLY weird dreams and the latest was a series of zombie dreams.  In some of them, I was fighting zombies, but in the last one, another Harry Potter book came out and all the characters were on the run because there had been some sort of zombie apocalypse in the wizarding world (in was unclear whether it also include the Muggle world).  It was really dark and scary, and we were all like, "Hmm, it doesn't really fit with the other books."  Other than that, we didn't seem to think there was anything off about it.
