Derse is pretty strongly linked to Rage, but it’s also got strong links to Void, Doom, and Blood. It’s a society, so in general it incorporates all the Aspects, even if it’s cultural conciousness might favor some more than others.
Gamzee was a Prospit rage dreamer, so we might look to him for clues. Nihkee Moolah’s also Prospit+Rage, so she might give us more insight, too.
In general I’d expect a Prospit dreamer to tend towards being more passive, positive, and reactive to the world around them. They’ll think less about how they construct and present their personalities and be more inclined to go with the flow–though this depends on Class, too. Derse dreamers tend to be more methodical, intense, and self-directed by contrast.
