Thanks for the input! One of the things I was thinking is that, when they enter the dreamscape their OWN subconscious would recreate them into an "avatar" of sorts. So a person who in the real world had a thing for elves, would actually materialize as an elf. Given that, I agree about never having a dream where you didnt know how to do what you were trying. Thats part of whats awesome in a dream. SO its either similar skills, or create an alternate persona...same attribute but with fantasy skills. But how to get them to do it without giving it away is the question!
So I have a group that loves 7th ed. I like to run games in the scifi and and medieval genres though. Products like Cthulhu Rising are not 7th ed so it makes it difficult for new Keepers. So I have a scenario I want to run, where the investigators are allowed to enter the mind of an abuse victim and mental patient. The patient has crafted a fantasy style world in their subconscious where they retreat for safety. As the investigators arrive, they have to use medieval style weapons and what not as conduct their inquiries within a fantastical "world". How does one figure skills and such for such a place? Just use BRP?
