"where" the mind's eye is also variable. And may be moveable.
For a time, my mind's eye was 'on the floor, sideways, behind "my driver seat"'. With some effort, it is now 'in front' of me, closer than where my vision is, occupying some space between where my vision is, and where I perceive my sense of self to be.
The efforts were a combination of trataka flame training, training to remain conscious through the process of falling asleep (for lucid dreaming), and drawing (seeing an image, quickly memorizing it, and drawing it from the mind's eye projection {as in, literally trying to see the image on the blank page without access to the reference image}).
