Computers, but few and far between, and only in houses built of wood or stone, which are not at all the norm. 

Wandering groups of people, living in a world of lush green fields and sparkling lakes with brightly lit beaches, and every so often a fenced-in tennis court or baseball field (or possibly even Quidditch pitch, though I didn't see any in my dream.) Gravity much weaker than on Earth, despite the fact that they're somehow supposedly living on the surface of a giant star rather than a planet. Magic, anyone?

A tyrannical world (or possibly only country?) leader who can summon tornadoes from a calm sky and probably has other powers. The tornadoes start out very cartoon-like but become more and more real as they grow larger and stronger, and the summoner can control them but not entirely. 

A more local (or as local as can be in a largely nomadic society) leader who is kind and helpful, and resists the tyrant when innocent people (or at the very least children) are put in danger. 

Pairs of teenagers going to get squares of brightly-colored tissue paper attached to their cheeks to show that they're in a relationship.

Homes that consist of cloth roofs (complete with zipper and/or velcro equivalents so they can open up in a variety of ways) attached to frames with walls and floors of some unknown material, but no windows or doors (the roof serves as both, I guess?) except in the few that are multi-story and therefore not just a single room. No way to go between floors without going outside. These homes are the safest place to be in an emergency (even the two-floored ones which seem likely to topple over if the emergency happens to be a tornado or something) because there's some sort of (magic) safeguard, and they're portable, controlled by slight leg movements of a person sitting or standing near a specific, special window-hole in the roof that serves as a viewpoint. Don't ask me how it works, because I don't know.

Giant squares of cloth (maybe about the length of a small city block) being involved in some sort of competition for status or for resources or something. Those groups with velvety cloth can be expected to be more powerful. It's quite the sight to see three or four groups of five to ten people each holding one of these squares above the ground and racing to a certain spot on the landscape, especially if you see it from far enough away and high enough up to see the individual squares rushing along. 

A pair of young boys, neither much older than seven, who for whatever reason the dictator wants to get rid of, and so have to split off from their tribe? caravan? to go into hiding along with a single adult to take care of them. 

Their sister, a teenager whose life was going very well before this happened, who had just gotten tissue paper squares glued to her cheeks for the first time recently, suddenly having to part with her brothers, and having to maintain that she has no idea why the group of three left and that she's very worried about her siblings if she should ever encounter the tyrant. Except that when he comes, he doesn't stop to ask questions, even to determine whether the boys are actually there, before summoning a tornado. Her having to protect not only herself, but the little five-year-old who clambers into her home with her, and anybody who might happen to be in the lower room, from this and any other obstacles the leader might send, and steer the structure under conditions she is unused to. 

Overall, very crazy, and very interesting. It would make a very good story if it could be accurately written down, but this is the closest I can get, and it doesn't really capture what the world is like at all. So I'll just hope for another dream set in this world, allowing me at least to see how things play out, get a sense of the world. 

Why did this never publish? ...Darn it, Wattpad, work with me please.
