I can no longer rotate or even imagine 3d objects.
My lexical memory is very high, and I have long running echoic memory so I can post process audio but a 0.1 second visual flash?
Unless my brain picked it up and had time to parse out the numbers into lexical storage I would not be able to go back and recall it at all.
I don't have congenital aphantasia and it's clear to me that there are certain kinds of background processing still occurring in my subconscious, it's like a unidirectional connection between parts of my brain that was once bidirectional.
