Dreaming outside the box

Joe provided an illustration of Jung's graph of psyche in this post. I'd just listened to bits and pieces of Machine Dreams by Little Dragon thanks to Balder's tip. So I responded thus:

Speaking of dreams (from this post), and as it relates to Jung and sub-unconsciousness, it seems that it's really our conscious rationality (ego) that does all this 'ordering' of things into tidy little boxes (or cubes). Whereas when we go below the surface in dreams things are not at all tidy or in sequence, and go all over taking tangents ever other second, with no particular order or sense whatsoever. What does that tell us about our order, the most recent and superficial layer of psyche?

This thread explores that question.
