If you don't see images in your mind, do you see images when you dream?
If you don't have an "inner voice", do you hear sound when you dream?
I have no point I'm trying to make here. I just wonder if there's a correlation with dreams.
If you place your hand on a wall, then close your eyes, then remove your hand, I suspect you'll still feel where the wall is. Even if you picture something completely different in your head, the wall is still there I suppose? My guess is that my extend proprioception (or whatever the right name for this would be) is more fine tuned and apt than someone with a mind eye, but I can't really know. :|
I also do not hear sounds while dreaming, but then again I don't really have an inner monologue anymore, that went away at the same time I learned programming and I don't think it's a coincidence. I do verbalize in my head when reading conversation-like stuff (HN, slack, etc.), but you won't catch me with any internal monologue while reading ingredients, jira tickets, etc.
While dreaming, I can have conversations but there's no gradual arrival of content, it's instantaneous, it was not yet "said" or it was.
