I would describe it this way: my mind kind of has a scratchpad of sorts that's separate from what I see or hear. It's a dream-like space that you can conjure a vague image onto that's visual in nature but distinctly different from literally seeing out of your eye and not in real space. If you are able to recall and play a song you heard in your head - it's reminiscent of that, but visual. I often do both. When I was younger I often visualized words in my head as I said or thought them.
