Here is the main thing of great importance that is tricky:

The unconscious is just that...unconscious...

And the conscious is just that...conscious...

What we want is additional info for problem solving or creativity or learning. We have to build bridges between the conscious and unconscious. Thresholds are important places of transition. Image streaming is a threshold situation that allows us to build bridges.

But, when we pull something over from the unconscious to the conscious, thruout history, mankind has only been able to do it via poetry, art, images, fantasy, myths, fairy tales, dreams, projections. And to make it a challenge we tend to forget that the image of the black dog w/ the collar is an image from the unconscious that needs to be interpreted to be incorporated into the problem we are trying to solve.
