I'm glad you asked, friend! 

Don't Rest Your Head is a system (and setting) similarly focused around the concept of dream-logic. It has a horror-like atmosphere which is supported by the mechanics creating a constant downward spiral that continues until a character either dies, falls unconscious (which, in the setting, is as good as dead), or is consumed by their own abilities, the latter of which which transforms them into a nightmare-creature that starts the cycle anew. 

It's fundamentally a success-dicepool system with static TN, but the most unique aspect of the system is a pool of color-coded dice which correspond to different aspects of your character's skillset that can be mixed-and-matched for rolls, but have different outcomes depending on the relative values of each die-type.
