Different layers of consciousness I assume?

In a way perhaps, be careful with that thought too, its not quite that! Hard to answer :D

I am curious as to what they looked like to you?

Hmm, as I said, I haven't been remembering too much of my dreams because I shouldn't for now..
The latest experience I had with those spheres was a couple of days back when me and my girlfriend tried to sync our dreams. We've done it before a couple of times aswell
While dreaming, I felt like I was in two places at the same time, I managed to actually meet her, we were in some kind of desert, but all was pretty blurry. I was feeling myself sort of trapped to a lower sphere being... well, attacked or distracted in a way.

Does something govern these layers?
In a way.. yes. But that's something you shouldn't worry too much about now.
Many things "govern" the layers, you are one of those things. But as I said, don't worry about that part. Direct the energy of your focusing thoughts to proper purposes (:
