Last night I had a Cloud Atlas-level of complexity to my dream. It was amazing! So much so that I did not make the effort to try and remember it while I was sleeping (I'm a lucid dreamer) because I didn't want to miss anything. Actors I recognized were Liam Neeson, Nathan Fillion, Paul Dano, Morena Baccarin, and I think Charlize Theron. That last one is fuzzy.
It's not post-apocalyptic but post-societal collapse. Technology still exists but people can't create more and can't maintain it in the way it previously had been. I don't know why, if there was a power grid collapse or something along those lines. There were definitely electric lights, but on a smaller scale, like they were powered by localized hydroelectric power. It's almost a pantomime of modernity. Think the social construct of the Firefly universe mixed with the aesthetic of Bioshock--a '50s like faux-utopia/surviving on the frontier blend.
God I wish I could remember more! The final bit is freshest in my head (though Paul Dano's scene at a rickety tavern atop a waterfall was intense and Morena Baccarin flashing her breasts smacked of unnecessary Hollywood sensationalism). Liam Neeson's character was presumed dead, but he was actually a wanted criminal simply called the Arms Dealer. He'd lost one hand (no pun intended) and had an Aquaman-like harpoon prosthetic. Charlize Theron was his wife, who knew he was still alive, and was taking care of their kids. They lived under a bridge and it was intensely important that the kids know how to get in because the path was secret. I don't know what the danger was. I think Neeson was the "bad good-guy" trope.
I think I've already lost the rest of it. Ugh. I hope I dream this one again. I think it'll make a pretty intense story.
