It's the same for me. If it's an unaltered condition, it seems at least more common than lack of internal voice or eye :)

I love unintentional epiphanies :)

I can imagine odors decently. I didn't know this until I just tried it after reading your comment. But yeah, I just imagined what a jasmine bush smells like, my dog's poop, strawberry scent car freshener, baby powder, and distant brush fire.

My best guess is that I'm imagining them at something like 30% fidelity, and some are harder than others to synthesize in "my mind's nose"

It's not nearly as good as what I can visualize in my mind's eye, so your analogy is still helpful.

Yeah, I think I have a relatively poor visual imagination, but when I try to picture a specific object it's probably ~10% as vivid as actually glancing at it. When I try to recall a smell, it's probably more like 20% as vivid as smelling it.
