I have an inner monologue, but I wouldn't say I was like "hearing" anything. For me it feels a bit more like the muscle movements in my larynx are played out as though I was going to speak the words. I can imagine a voice speaking at the same time if I want, but that's not how it is normally.

I tried reading at the same time as thinking of different words. I can certainly read the words whilst thinking of different ones, but I can't understand what I read very well. Probably it could be done with practice.

However, if I have planned a sentence that I want to type, I can type it whilst listening to someone else or thinking about something else. It's slightly more error prone though.

I can certainly imagine pictures in my mind without any monologue running at all. But this also isn't my normal mode of thinking. It's not helpful because I don't normally associate abstract concepts with pictures, but with words and symbols and abstract memories of things that worked in similar situations before.

I believe I can recall all my senses or imagine them in my head. I don't seem to dream in words though, but in pictures, mostly. I'm also a much more visually stimulated person than an auditorially stimulated one.
