Neither can I. Well, I can wen I'm not reading. Scenes of my novels or fanfics will play out like movies in my head. But then I have trouble putting it into words. And vice versa. When I read, I have trouble visualizing. Even when reading fanfiction of t.v. shows, where there are specific people, that I know what they look like. I will hear dialogue in the actors' voices, but won't actually see them. There's a disconnect between words and pictures for me.
