Parallels
A group of ordinary people who live mundane lives all wake up together in a dreamworld/other dimension where they have superhuman abilities. This other reality is parallel to theirs, just with scifi/fantasy elements thrown in that are typical of a superhero universe. Part of the mystery is finding out how they are all brought to this other reality, and why they were “chosen” to connect as dreamers/heroes, but it becomes more difficult since the dream picks up where it left off if they go unconscious in the Superhero Reality/Mundane Reality, which leads to realities blurring.
I haven’t really explored The Mundane Reality parts all that much yet, so this is mostly the superhero aspects that I’ve been developing/posting 😅
