My husband can't visualize anything either. Sometimes I wish I didn't have the whole vision in my head because then I wouldn't be so disappointed when I hand to change courses and I don't want to.
So I'll ask this question for those of you who can't visualize: when you read, do you see what you're reading in your head line a movie or not? I have a very vivid image of a book I'm reading and of the characters. My husband does not. I also see numbers when I do math. The number lines are very specific and have been that way my whole life. I also see a calendar when I'm doing something with dates. So for those who don't visualize how a pool is going to look, do you do any of that with other things? My husband doesn't and neither do the others we've talked to about it. I think they all go together but I'd love more on my theory.
