These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Little Fears
Nightmare Fuel: The game RUNS on it. Pretty much anything anyone anywhere has ever been afraid of has the potential to become a monster. Among the many threats suggested in the book are clown demons who live to turn joy into fear, a fairy queen who may trap your soul inside a mirror for the rest of eternity and The Defiler, who is basically the avatar of child molestation.
