In episode 1, we got a really small scene where we hear Lee's dream in the barn.
In episode 2, there were unused audio files for some sort of dream sequence involving whoever died in the drugstore: http://www.youtube.com/watch?v=ISwyl5U654c&list=UL, at 5:31.
In episode 3, Lee sees Clem as a walker.
Should there be actual dream sequences in S2? Why or why not?
