Yeah, it does. Unless the dream causes me to have already pre-memorized the text by previously "knowing" what it's supposed to read as, the text always mutates during a second reading. I think Darien once claimed that he has no problem flipping back and forth at will in a book and reading the text *consistently* inside a dream, but I don't believe him. That's just impossible. :-)
