I remember very little about this dream, but here you go.
I was at the bus station in my town, where Yoshika and another Touhou character (possibly Satori) were talking to my parents.
Apparently, her and possibly Satori managed to get themselves stuck in the outside world, and needed our help.
Cut to an aeroplane, where a ton of touhous were sitting at a table. I remember Yukari, Yuyoko and Yoshika, who was asleep, and kept slapping Yukari with her arms.
ZUN was there too, and kept trying to give me lemonade.
This is my first post too, yay!
