This probably won't make sense unless you're familiar with both Homestuck and Yume Nikki. The crossover only occurred to me because of the Yume Nikki-style sprites that someone submitted to #Homestuck-Fans (to whoever made those: I FORGOT WHO YOU WERE I'M SORRY). My idea was basically: What if the death of dreamselves on Prospit/Derse meant you had to wander through creepy-as-fuck dreamworlds and collect effects and things
I know, it's an amazing concept and I'm sure your mind is blown.
