I think I am pretty similar to you. When I was younger I used to build all sorts of things with paper and cardboard and used to imagine the whole thing in 3D and design its cutout template all in my head. I learned about aphantasia a few years back and it sounds very inconvenient to me.

I also have a habit of playing around with imaginary worlds and stories in my head and I pretty much visualize whole scenes and sequences in as much detail as possible. I wouldn't be able to do that with aphantasia.
