I always think in pictures. Since I was younger my mom associated words I had to learn with pictures. Than after that reading a book saw it in pictures, some conversations I see in pictures. I memorize everything in my high school I see the whole thing. Say I go to my Uncle's house or Aunt's after 2 times, I know the whole house. Like in August this year I went to my Uncle Bob's house first time in 11 years, I knew where everything was kitchen, bathroom and the bed room I was going to sleep in. After not being in high school in 3 years I believe I was able to draw a whole picture out of the high school where everything is.
When I give directions, I see everything the trees, houses turns and such. Than I give directions by that, like go down the road when you see a open space of land with 10 huge rocks on your left hand side turn down that road. People told me that it's much more helpful than the directions my mom gives them.
I think in pictures, a lot.
