Unfortunately, I forgot most of my dreams & most of this dream, including the most important parts; so this dream is incomplete and a little confusing.
This dream took place in a version of our world (Earth) where each person (human) had a unique ability (power / superpower / quirk) that they were born with, so it was natural, I assume; similar to the Japanese anime (animated) TV show My Hero Academia, except more realitistic & grounded & limited.
There were several unique abilities or types / categories of abilities, and each person only had one unique ability / type / category of ability.
