The Science of Dreams

I don't know that we need to have a common vocabulary in dreamland for there to be a science of dreams. Young, by the way, a psychoanalyst in the freudian tradition, although he eventually broke from freud, did believe that there would be these archetypes and one way or another they'd come out. I just wish i knew which kind of attention to pay to which dreams and which functions those dreams are serving. That's all i'm asking for.
