Think of what you see (with you eyes) as a stage, space, or, in computing terms, a buffer or something like that. What I imagine in my head does not compete for space in this buffer that much -- it's like in a different stage, a different space. I know something I imagine lies in imagination-space not in eye-vision-space. Those two spaces are probably merged somewhere[0] so they can use similar recognition and abstraction engines in the brain, but this information of what comes from which one is maintained (like you can distinguish between senses, between the auditory stage and the visual stage without thinking). [0]: I believe this explains how, while I can do all this visualization, it's difficult to simultaneously "grasp" both spaces -- it's like both are there, but when I switch to mind space the visual one goes to the background and I can't process it too much.
