Alternate DitV setting?

[opsneakie]

I've been playing Dogs and Afraid recently, and I've been wondering about possible adaptations of the system:

For a while now, I've been toying with the idea of running a game in which the characters are dreaming, trapped within nightmare dreamscapes and in need of escape. I haven't been able to think of a good system to do this, but since playing Afraid I think the Dogs system might work fine with a few adjustments. I like the status conditions like Afraid has, and I like the relative simplicity of the system, but I'm not sure how one would adapt it to run a game where the characters are trapped within a nightmare world and can dream things to life...

Does this idea sound at all interesting or worthwhile to anyone out there?
