I also think in pictures, movies, 3D scenes, and abstract concepts. Very rarely, like when I need to plan what to say, I might have words intertwined in my thoughts. The book Thinking in Pictures by Temple Grandin explains this well.

I THINK IN PICTURES. Words are like a second language to me. I translate both spoken and written words into full-color movies, complete with sound, which run like a VCR tape in my head. When somebody speaks to me, his words are instantly translated into pictures.

…

When I was a child and a teenager, I thought everybody thought in pictures. I had no idea that my thought processes were different.

…

When I do an equipment simulation in my imagination or work on an engineering problem, it is like seeing it on a videotape in my mind. I can view it from any angle, placing myself above or below the equipment and rotating it at the same time.

…

I create new images all the time by taking many little parts of images I have in the video library in my imagination and piecing them together.

…

To create new designs, I retrieve bits and pieces from my memory and combine them into a new whole. My design ability keeps improving as I add more visual images to my library. I add videolike images from either actual experiences or translations of written information into pictures.

…

When I recall something I have learned, I replay the video in my imagination.

…

Like me, the mnemonist had a visual image for everything he had heard or read. Luria writes, “For when he heard or read a word, it was at once converted into a visual image corresponding with the object the word signified for him.”

…

It wasn't until I went to college that I realized some people are completely verbal and think only in words.

...

When I invent things, I do not use language. Some other people think in vividly detailed pictures, but most think in a combination of words and vague, generalized pictures.

...

I used to become very frustrated when a verbal thinker could not understand something I was trying to express because he or she couldn't see the picture that was crystal clear to me.

...

Unlike those of most people, my thoughts move from videolike, specific images to generalization and concepts. For example, my concept of dogs is inextricably linked to every dog I've ever known. It's as if I have a card catalogue of dogs I have seen, complete with pictures, which continually grows as I add more examples to my video library.

My memories usually appear in my imagination in strict chronological order, and the images I visualize are always specific. There is no generic, generalized Great Dane. However, not all people with autism are highly visual thinkers, nor do they all process information this way. People throughout the world are on a continuum of visualization skills ranging from next to none, to seeing vague generalized pictures, to seeing semi-specific pictures, to seeing, as in my case, in very specific pictures. I'm always forming new visual images when I invent new equipment or think of something novel and amusing. I can take images that I have seen, rearrange them, and create new pictures.
