Sven Birkerts describes the experience of reading a novel:

The question comes up for me insistently: Where am I when I am reading a novel? I am “in” the novel, of course, to the degree that it involves me. I may be absorbed, but I am never without some awareness of the world around mewhere I am sitting, what else might be going on in the house. Sometimes I thinkand this might be true of writing as wellthat it is misleading to think of myself as hovering between two places: the conjured and the empirically real. That it is closer to the truth to say that I occupy a third state, one which somehow amalgamates two awarenesses, not unlike that short-lived liminal place I inhabit when I am not yet fully awake, when I am sentient but still riding on the momentum of my sleep. I experience both, at times, as a privileged kind of profundity, an enhancement.
