I'm putting this in the spoiler section since there are mild spoilers in this fantasic interview, but nothing too intense.  I gotta say, Laura Prudom rocks.  She, myself and a few fans had a discussion on twitter one night about the possibility that season six or seven was a dream after our series of speculation articles were posted here and getting a lot of discussion.  She asked the question to Jared, Jensen, and Sera!  Jared and Jensen love the theory, but Sera says it's real.  Oh well, we'll see how it all plays out.  This is a really enjoyable interview.
