Okay, so I just had the most crazy dream. Well, not the dream itself, the inspiration for it was obvious, but the ending.
First off, might be important, in my dreams in general the boundary between movies/games and "real life" is very blurred. It isn't uncommon that I will be both watching a movie and inside the movie simultaneously. So this could be a movie.
So, the dream:
I'm part of a group travelling through a world that basically looks like the far future, after the apocalypse. Humanity is near gone, most cities are overgrown by forests, and intelligent dinosaurs rule the planet. It is implied that my group was thrown into the future due to time travel experiments and we are trying to find a way back.
We are also carrying a video tape with unknown contents.
Occasionally there are flashbacks to shortly after we arrived in the future, before we know about the dinosaurs or the fact that humanity is gone. In the flashbacks, we are looking for the lab that sent us into the future, hoping it can send us back.
(If this seems awfully coherent for a dream, it's because I'm leaving out the stupider elements, like the flying sharks and the boardwalk safari subplot.)
Anyway, long story short, we eventually find the dinosaur temple time portal and are about to return to the past. Then the final flashback:
We find the lab, which has been completely destroyed. Plants are growing all over it and all of the machinery is broken. There's some signs of dinosaurs but we're still ignoring them.
Inside the lab, I notice a flickering tv with a cracked screen. There is a barely visible video playing on it. I look at it.
Slowly, I walk over to the tv.
"Hey," I say, "do any of you remember that movie from a few years back? The one about dinosaurs and the end of the world?"
"Yeah, why?" one of them answers. "That was a dumb movie."
"It wasn't a movie," I say, slowly turning towards the "camera". Behind me, the (silent) video shows the same scene, but lagging behind a few seconds. "It was a vision from the future. It's real."
I wake up/cut to black.
