Answering one of yesterday's anons: the main lore difference between prospit and derse dreamers is that prospit dreamers get to see the clouds of skia, while derse dreamers are farther out in the furthest ring, and I believe also hear the whispers of the horrorterrors. This creates the optimism/pessimism theme from the official quiz.

It’s just not really reductible to “Pessimist vs Optimist” though, there’s a lot of nuance and specifity to go through in each personal case.
