I discovered about ten years ago that I have Aphantasia which is where you don’t see images in your head. I always knew I couldn’t see images. I just didn’t realize other people actually saw stuff when they close their eyes. As a result, description has always been boring to me so I have to work extra hard to include it. But it’s kind of fun to try to capture something in words that will paint a picture even if you can’t see the picture that’s painted. I feel a little bit like Mozart composing after he went deaf.
I’m more interested in what the characters are saying or doing than in what they look like or what they’re wearing. It helps to think of the setting as a character in the story as much as possible, but that isn’t easy.
