Reality refers to what is going on in our world, whereas utopias (an idealized “better version of a world) and dystopia (sad/dark version of a world) aren’t real.
Novels like these can help us understand our world better by comparing it and seeing what we have and don’t have. Dystopians can show us a dark view of what can happen to our world whereas utopias can help us see how to improve this world.
I hope this makes sense hahaha
