I loved it. I started out convinced that the TARDIS had to be real, of course, then started wondering just about at the time the Doctor did, and then actually suspected neither one was real when I saw the "Lord of Dreams" being so helpful - yep, you beat me, etc.
When the Doctor said "I know who you are - there's only one person in the universe who hates me that much," I actually shuddered and thought "Is it HIM?" But then I sort of got caught up in the storyline and forgot all about that thought.
Isn't it interesting that even when "everything dark in him" is in control, what he does is force Amy to make the choice he needed her to make anyway, because apparently the whole universe somehow depends on it? And once she HAD made it, he started being terribly obvious so the Doctor couldn't help but catch on that this was suspicious behavior for a villain. Even the dark in the Doctor works to save the universe...
And Amy was RIGHT. He DID tell her in the end!
Blowing the pollen out the door seems a bit risky to me, though - yes, I know the universe is really, really big, but with the way things go in the DW reality, it's just bound to drift somewhere and bother people he knows - possibly in Cardiff or Ealing. *g*
Anyone else who heard "Lord of Dreams" and couldn't help thinking of Neil Gaiman's Sandman? (Yes, I know this wasn't the ep Neil wrote.) The funny thing is, though... Morpheus actually has a lot in common with the Doctor. Including self-loathing. (If you have no idea what I'm talking about, run, don#t walk, to the nearest bookstore and buy all ten volumes of the most brilliant graphic novel ever.)
I'm sure Amy noticed that he did *not* deny that he thinks all of that about himself. And I hope he calls him on it later.
Did anyone else notice how much the Doctor apologized in this episode? He apologized for calling the village life dull, he apologized for snapping at Amy when she said she was cold... Of course, Ten apologized a lot, too, but this was different. Maybe he was feeling guilty becuase on some level he knew all along that he was the one causing the trouble.
Why birdsong? Seems a strange choice.
I'm going to re-watch this episode as soon as possible. It moved so fast, I know I missed a lot.
