I’m like that. Weirdly, I can plan out things in my head, like how a piece of furniture should be designed and made, but it’s not a visual process. I just seem to know how it should be. I have virtually no visual component to my imagination, but I can basically listen to entire songs in my mind. It’s only recently that I realised that there are people out there who have no internal monologue! Like their brain is just quiet, and they can get on with stuff without it getting in their way! That’s weirder to me than the presence/absence of visuals etc
