What if it was all a dream?

****Spoilers Ahead**** After Shaw is told the foetus inside her is 'not a normal foetus' and David gives her an injection to relax her prior to hyper sleep, she is then shown as the tech's try to waken her for preparation. What if she didn't wake up and attack them? What if everything that happened after that point was all just a dream, and she is nestled in her cryo chamber on the way back to Earth? I like that idea, it would make sense of a rather contrived set of circumstances that happened afterwards. I know, I know, it's unlikely, probably impossible. And cheesy, oh so cheesy! But the thought of seeing her awaken at the start of Prometheus 2, having had her baby extracted, and now on Earth would probably be more interesting than what's likely to happen! And I could still hope there is some life left in the franchise. Regards Skybird
