I am a bit this way, mainly for faces. I can’t conjure a face in my mind’s eye. I can’t tell you what my wife’s or children’s faces look like, unless I’m looking straight at them, and even then my description is going to be useless because I can’t bring up anyone else’s face to compare them against.
I can visualise parts of faces: eyes, nose, the curl of an eyebrow, the purse of a lip, I just can’t put those parts together into a whole face.
I can recognise faces well enough. When I see my wife’s face, I know it’s her. I just can’t remember what she looks like if I’m not looking at her.
