I haven't been formally diagnosed but I'm definitely on the very low end of visualization. But I'll answer for myself:

While I'm dreaming and unaware that I'm dreaming, it's like I'm in real life. As soon as I start to wake up at all, everything fades to black almost instantly. I recall the experience as if I lived it though dreams are strange so it's far less consistent than a normal narrative.

What kind of memories? I often completely fail to encode and remember highly visual details - like what color hair someone has, what shirt they were wearing, and so on. But I could recall the name of the building in which my college showed the Matrix in the fall of 1999 because I could remember which way I walked there.

I recall audio strongly and can hear the voices of various characters in my head. I can do passable impressions of quite a few characters. I can tell you the story in detail, but if something hinges on a visual cue I will completely fail there.

I mostly talk to myself in my head. It's a running narrative. If you'd like a specific example, give me something more meaningful than "imagining".

If I want to read something and retain it well, I will hear it in my head in my internal voice as I'm reading.
