I dunno. I can hear music, it is muted in my brain but I basically have a audiographic memory. I can't visualize anything though. It is so weird. Basically my internal DNN can record and playback but not yet generate new things like stable diffusion either.. I suspect my musical training at a young age played a role in this as well as listening to lots of classical music.

Psychologists and neuroscientists can tease these things apart.. in the article they talk about it. But aphantasia is only recently being understood so methods to quantify the degree will improve.
