> I would say they are more “visual” than verbal in nature, and therefore I often say I think more visually than verbally

I am the same way, for me it's that thoughts feel multidimensional in terms of structure as well as temporal ordering, while language/verbal communication is often linear and ordered in particular ways. So much is lost trying to put thoughts into words I often don't bother unless I have to.

Whereas visual languages feel more naturalistic.
