I'm a software developer and I have kind of like two different "address spaces".
There is the normal visual + auditory address space. And there is the "intuition space" which is similar to the first one (e.g. I can imagine a 3D object and rotate my viewpoint around it, simulate conversations, etc), but it's with limited detail, more like black and white unless I concentrate more. I can "hear" there but it's separate from normal hearing.
It's super-useful in programming, as i can imagine code in some kind of 3D space, where I can move in and out of different functions calling each other (I still imagine them mostly as text though), so I can remember them pretty well.
