Dream Army is set in the modern world, for all intents and purposes, right now. Imagine that you are one of only a few who wake up one dark morning. You find that the world has stopped, that almost everyone else is still sleeping, and that while the world wastes away in sleep, nightmares walk the Earth, feeding. You are one of only a few people who are awake, and you find that your dreams, which now come to you while awake, give you power to resist the darkness.

Good questions. I left a lot
Good questions. I left a lot open in the brief treatment but I see the gross conflicts of surviving without a lot of technology and surviving being hunted by roving nightmares. There are also subtle conflicts around staying safe or venturing out, figuring out what has caused what happened and conflict between the wakeful themselves. I also see political conflict between rival factions of geeks with superpowers, each responding to the world catastrophe very differently. The Big Bad is also out there with some kind of plan behind it all
The strengths of this setting
The strengths of this setting remind me of "Wraith: The Oblivion." In other words the setting as a whole really grabs me, but I'm really curious what game play would involve.
What would players do? I'm not asking so much here about mechanics, but rather the action of the game. What's the conflict? I'm having a hard time seeing beyond 'fight the nightmares.'
