I understand what you mean. I believe that the authors would contend that what you're describing is a typical attentional state for an awake/aware human: focused mostly on one thing, and with surprisingly little awareness of most other things (until/unless they are in turn attended).

Furthermore, even what we attend to isn't always represented with all that much detail. Simons has a whole series of cool demonstration experiments where they show that they can swap out someone you're speaking with (an unfamiliar conversational partner like a store clerk or someone asking for directions), and you may not even notice [0]. It's rather eerie.
