As an aphantasic, I remember what I know about the Mona Lisa. I know that her lips are famous, I think her face is placed more to the right, and her hair and clothes are dark. I am not sure if you can see her hands, I would have said you cannot (I checked and I am wrong).

Apparently, I was never aware enough of her hands to know that they were in the painting. And I could not tell you how her hair lies or what her smile looks like.

It is not word-based, but just knowing. I just know the clothes are dark. There is no experience that can be edited.

When I collect the characteristics to write them down, I think in words.
