Vague Dreamposting

A somewhat dystopian timeline. I was either in first or second grade when I had this dream.

I was living in the apartment complex, Greens of Turfway. But while the surrounding apartment buildings were the same, where they were located was not. Think like 1800's western city with cowboys. Vaguely city-like but no skyscrapers, brown everywhere. So much brown you could swear the whole world was in sepia. Dust and dirt billowing into the air and going up for miles into the atmosphere, even making the clouds overhead a light brown color. It was cloudy. Light, but no sun.
Rising above every other building, sat C3PO and R2-D2, using an oversized billboard like it was some sort of couch. If you looked out the windows facing the front of the apartment, you could see them. It was dangerous to peek out of them, or even go outside at all. C3PO was armed with a laser gun. Don't remember if R2-D2 had any lasers equipped. They would shoot at any human they spotted. We stayed hidden inside of our apartment, occasionally peeking out the window to see all of the commotion and... I guess hoping they would leave? My entire family huddled down in hiding, including our cat Fancy, who somehow seemed to know the danger. (May Fancy's little kitty soul rest in peace)
Behind the apartments, it was surprisingly more vibrant. Not as sepia-toned as out front. There was green grass, a blue sky. The trees swaying gently. A kid who lived nearby called out. Tan skinned, dark hair, brown eyes, glasses, gap tooth. Racially ambiguous but if I had to guess, I would assume Arabic? Middle-Eastern? I don't remember his name, only his face. He yelled "Tornado!" and one randomly but rapidly began to form from behind the apartments. The need to huddle down for safety increased tenfold. But something weird happened. Suddenly, the entire back of apartment was ripped off, leaving only the front wall and about a foot of flooring, maybe not even that much. More than 4 inches. We were dangling, holding desperately onto that last bit of flooring to avoid being swept up by the tornado. We formed some sort of a human chain, holding each other's hands. Fancy was at the very bottom.
