Yeah, I think there are two distinct types of visual spaces in the mind. When I'm tired, meditating long (rare), or otherwise in an unusual state I can sometimes access the one that feels much more eyeball derived. Very rarely I have been able to access it just by trying in a quiet place with the right kind of mindset.

This kind of visual feels like it is coming from my eyes, as opposed to the more common and controllable (but less compelling) kind of visualization. This 'channel' is in the grainy blackness space of closed eyes, in front of the face, like where you see color blotches when you press on your eyes or look from very bright conditions to darkness with eyes closed. Except that it can become no longer very dark at all and even sometimes have rich, vivid colors when I get a good session going.

I can't lucid dream btw, and this state is exclusively around the boundary between sleep and wake, and it's distinct from a dream IMO because every dream I have ever remembered I am a subject experiencing the dream, whereas this is pure visual like watching a scene TV (except I can sometimes decide what happens, though it's much easier to morph what comes on automatically than shift to an entirely new scene without breaking the spell).

But usually I just visualize things in the channel well behind my eyeballs, in brain-space. I can do this second kind with eyes open (though with better clarity with eyes closed). The first kind is only eyes closed. For me the background can be dark, white, or complex scenes(abstract or real-world). I have very fine control over detail in the objects if I want, but they feel much less real especially in the sense that they disappear the instant I stop focusing entirely on them, unlike the first channel which persists since I am in some sense in an unfocussed state already.
