The weirdest thing about most of my dreams is that neither myself nor anyone I know is ever really in them. My brain just quite literally writes completely fictional movies for me to watch, with made up actors, made up places, etc...
One of the ones I remember the most was about two androids (a married couple???) are on holiday at a remote resort surrounded by forests on all sides. It's not explained, but my brain just knows that this is a world where humanoid androids have entirely replaced biological humans and have essentially just "adopted" their lifestyles, but we don't know what happened to the humans yet.
In the middle of their stay, two things happen simultaneously; first, the nuclear reactor that powers the resort begins to go critical and they need to escape. But outside, a horde of savage humans, essentially devolved cavemen, attack the resort, trapping them inside. With no way out, they find out that they can delay the meltdown by putting pencils on top of each heat vent on the floor (because sure, brain...why not?).
And then I woke up. Never did learn how it ended.
As challenging as it would be, the Fallout universe.
Don't know why. I just feel like in the Fallout universe, you can be anything you want to be as long as you can convince enough people to back you up. Those same people might eventually stab you in the back, but still...vigilance is a small price to have the freedom to climb from a nobody stumble-bum to a czar of your own city-state.
