Just woke up from two very vivid ones.
In the first one, it started with me (or the person whose point of view I was sharing) and a friend escaping from a rural town with a very controlling government. Curfews, most entertainment banned, that kinda stuff. We managed to board a bus heading for the capitol, but when we were approaching it, we somehow entered a parallel reality where bad events made people happy and good events made them mad or sad. Being polite and friendly was still the norm, but people just did violent and destructive deeds normally. I and my friend tested this out at the train station we woke up in. I eventually got a job at a McDonald's as we were trapped, and the climax was where I couldn't take it any more, snapped, and threw children off of a high rooftop to a cheering crowd down below who paid them no mind as they splattered.
Then there was an intermission where I played a version of Smash Bros where any character could use any loveseat and the stages were a fucking visual mess.Though one could use various styles for stages, like an N64 or Gameboy Color version of a Mario stage.
Anyway, the next major scene involved me teaching an alien the basics of human existence. Like they knew absolutely nothing and saw everything we did as strange, unnecessary, or illogical. Had to explain to them how we preferred eating food three times a day instead of subsisting on a weekly diet of paper. They were very interested in words and their meanings so I'd constantly provide words for the concepts they wanted to express. They were also very confused about the concept of underwear. The only difference from this world and the real one was a system of geothermic-based train systems under the Earth's crust that people used to get around, and the lava was neon teal.
It ended as I was becoming exasperated by my mom not being patient enough with the alien.
