Hi, I just joined! Love this movie to bits.
Anyway, my stepmom just watched this movie and came up with a very interesting idea.
She thinks that Roberta Sparrow and Karen Pomery are either the same person(through time travel though I don't think so) or they are somehow related.
It makes lots of sense really.
Examples of proof:
-Pomery not only pretty much hooked Gretchen and Donnie up, but also led Donnie to Sparrow's cellar because the last thing she told him about was "cellar door"(all of this leads up to frank's murder all in all)
-Pomery didn't wake up at the end when all the "manipulated living" did from their dreams(just sorta a strange point that makes her different from everyone else)
-Sparrow used to work as a science teach. at Middlesex High and Pomery's husband is the science teacher and had the book. Pomery's choice of book was ironic compared to what happened at the school(The Destructors, a good storry also)

Well, I don't know if you guys really dug that deep into the whole movie, and I don't even know if any of this is relevant and worth while, but I found it interesting.
Tell me what you guys think!
Aloha
