This sounds kind of cool (If I'm understanding it properly)

I think I have done something similar before where my partners character was dreaming (there was a sub plot as to why but I won't get into it) and in his dreams I had my character, the dream keeper and she acted as a guide for him and so on and so forth. 

It was good but unfortunately the RP fell a bit short and died out.

If you'd like to try that I'd be more than happy to RP with you (^_^)
