I can close my eyes and see a picture or even video of any scene, from any angle, that I have seen before or that I could arrange the details of in my head, as if it were real. I don't even have to close my eyes, but it's more vivid if I do. However, I have trouble visualizing faces in great detail, or even much. When I try to recall a face, the harder I try to recall it, the more blurry it becomes. Aphantasia seems... hard to imagine. But evidently it's real. I imagine closing my eyes and being unable to summon a mental image of objects or persons. It's almost like being blind, but only when one's eyes are closed, and that's very weird. The most interesting question about aphantasia, for me, would be just how much it affects one's ability to deal with concepts, especially visual concepts. It's a question one might have about visual impairment as well. But it's clear that it doesn't seem to matter much. I know brilliant blind people -- it doesn't seem to slow them much if at all, and even seems to help them to some degree. The effect on conceptualization must be very subtle indeed -- a testament to the neuroplasticity of our brains.
