Inception?

So, whose else spent the morning after seeing it trying to figure out what exactly happened at the end of the movie? 'Cause I sure did...

I thought the most confusing part was the begginning, where you have 15 minutes of things happening without any explanation, but I thought it made quite a lot of sense in the end, at least as much as a film like that could do

Oh, yeah... I was left scratching my head trying to fit it into the scene that followed it. Then I figured it was going to bookend somehow, once it became clear that the two scenes didn't fit together. Was not expecting it to do so the way it did, though.
