What's the Difference Between the Unconscious and the Totally Unconscious Perception?

We have unconscious perception, which is your sensory systems taking in information and using it to control behaviour at some kind of low level. And then there's conscious perception that is attended, sense perceptions that are conscious in this strong way where we can report them. But then there's supposed to be a middle position that is stronger than the the unconscious one. It is conscious, but maybe i'm not thinking about it, not noticing it, not reporting it. So whats difference between that middle one and the unconscious and the completely unconscious one?
