You could always have the demon as a watcher wherever my character goes, then the subsequent dreams can be caused by simple eye contact, then the more sexual and vivid the dreaming gets, the more the demon can interact with me on a more physical level. We could get to the dreaming quite quickly so that the stalkerish watching doesn't become too boring for you :P

Well the thing is.
If I interact with you outside of the dream prior to taking a fleshy form then it somewhat ruins the magic.
I like the idea of a dream becoming a reality, you'd think you were going mad.

I'm a demon though, I can stalk your dreams easily enough. ;3

Oki doki, think we can do the other rp after this one then? Don't wanna take on too much.

Need to talk about anything else now, or are we good to go? (if so, who's starting?)
