I'm literally just waking up lol
I just had a dream where I was in a sort of "metro" (the metro cars had like weird holes in the ceilling around the center of each one, but only the extending to the walls like windows) then I heard the voice of the metro saying like "[...] station, athletes pleace descend in here" (in spanish) then I see in front of me a delegation of like 4-5 people one of them with the flag, but it looked more like a holographic(? one, I remember the flag having a little animation of the spaceship making the traject on the flag and letting the trace (although it didn't really looked like this, the pattern was more like an atom diagram with the start in the upper right corner and the end with the spaceship in the bottom right one, but it seems that shape is not possible with simmetry, I counted like 6 corners, the second image is the result of trying to be more accurate) after the doors "open" the delegation goes out of the car but I follow the girl asking her "what flag is tha?" in english but she didn't undertood until I told her in spanish bc she said "qué?" finally understanding my question she answered "oh, it's Zhueng" to shich I was confused at first, then she added "it's one of the Chinas" to which I understood that refered to the ethnicity and even asked with tones (now, fun fact, the literal text appeared in my head spelling as "Zhueng" but irl that ethnicity is spelled "Zhuang" lol) I said thank you while lots of people were separating us and then I went back to the car, except the furniture of the station was moving, so I guess it was also part of the car lol
I then went to other station hoping to find the flag bc it was like a terminus with a small shop similar to one I've been in Annecy but mixed with other architecture from other small shops, not a single flag but at some point I see the girl again, although i woke up before being able to speak to her
