Okay well before, when I had aphantasia, I did not experience things I "pictured" in my imagination as a visual sensation. It was as if my imagination was 100% linguistic, so if I imagine something I would just describe it to myself. I could describe something with a lot of detail, even! However, it only ever felt like I was providing a literal description of an image, rather than feeling like I was able to picture something.

I really do think it just comes down to how you feel your imagination.
