I, too, have a small-talk module running nearly constantly. It is English-based, but sometimes doesn't translate over to actual words. However, I'm different: I form mental images all the time. I create them too. I might be putting a mountain here or there, all narrating it with my spoken inner monologue. I'm like this when making art (visual art) as well - I narrate the motions, making noises with pen strokes and finishing paint brush strokes with something akin to a sports presenter on the radio. The combination of these two means I can get a mental image in my head that I've narrated to myself to build it, yet cannot describe it aloud in words without changing thought modes.
