Both memory and imagination are different from visualisation which is what aphantasia references. I can remember what an object, person scene etc looks like, I can also imagine objects, scenes as I put together memories to create the object or scene in my mind, but I cannot summon up any vision of that memory. Faces are different, I cannot imagine a face.
When I paint an imaginary scene, I mentally draw the scene in mid air, placing sky, mid ground and foreground etc as individual elements, but I cannot visualise the scene I imagine until I re-construct it on paper.
I have never found the inability to visualise a problem, if you have never had it, you don't miss it.
