Really weird dream. Post-apocalyptic world. I don't know how civilization fell, but the survivors were living off the scraps and remnants of our society. Few people were left, and those who'd managed to survive had it rough. The biggest concern was protecting ourselves from the dinosaurs who now hunted what was left of humanity. Dinosaurs? Yeah, go figure. In the dream I never saw a saur, but everyone talked about them all the time. T-Rex was the biggest worry, and I spent the whole dream extremely nervous that I'd run into one and get gobbled up.
