Complete 5 for me. Also, I have an internal voice, but that voice is just me. Basically just putting thoughts into words so that I can express them, nothing different from whatever the "I" or "self" is.
For the record: I always score very high on tests of spatial memory, those tests where you are supposed to have to rotate objects to find the answer, and stuff like that. I enjoy reading fiction; I like reading more than watching movies for the most part. And in general don't feel like I'm missing out on anything, or that aphantasia gives me any problems thinking at all. I often can't tell who someone is from seeing their face, but I think that's the autism.
