To add something similar: I am now at the point where maybe a few times a day I can visualize a glimpse of a memory, but otherwise it is blank and I have no visual dreams. But it does not hinder the ability to think about complex systems in any way. My day job involves making 2D technical drawings from multiple angles, 3D modelling, and of course to come up with the solutions before putting in the work of drawing/modelling stuff.
