When I visualize some thing I don't literally see it in my field of view but I can still 'see' it. It's similar to audition(hearing in your mind). Read something out loud in your mind or play a song in your head. Its the same thing you don't literally hear it but you do 'hear' it.
Yes but that was my point: I suspect (I can't be sure of course) that this is a limit of the English language. We call it "seeing", but it's not. If it would be real seeing, you would visually see the thing you are visualizing in your field of view, as if it were literally there (like in a dream).
