I think I used to be able to visualize earlier but by the time I learned about aphantasia I had already gone years without it.

Why I cannot say.

Sometimes when I get a lot of sleep and relaxation I think I can visualize in ny head.

Oh, and I can visualize at least one relative, but only a certain passport image of that person.

And I can draw to some degree, so I clearly know roughly what things look like even if I cannot visualize it internally.
