Somnus Engine

Somnus Engine is a unique solo role-playing game designed to be played entirely in your head as you drift off to sleep. It's a system for light, creative storytelling without any dice, cards, or apps.

The game uses a clever "Calendar Cypher" mechanic where you mentally combine a number you think of with the current date (for example, today is the 5th) to generate a random result from 1 to 9. You create a simple character defined by their Agility, Body, and Control, and then navigate a dreamscape of your own imagining. When you face a challenge, the game's oracle tells you whether you succeed or fail, with results ranging from a decisive success to a critical failure that twists the dream in unexpected ways.
