I think he's approaching it more like this:

In your dream, you find the "ideal" version of yourself - I would probably look for "Rock Star Chris" or "Bestselling Author Chris" or something - and in your heightened state of problem-solving and other paranormal dream-related phenomenon, you would basically interview this "ideal" version of yourself. You'd probably ask questions like, "Well, if I'm gonna be a rock star, how do I get my music out to the world?" and your idealized self (who is actually just a super-focused version of YOU, using YOUR sleeping brain) will answer accurately.

So yes, I believe it.
