That's one of the FAQ's in the piece:

8. Do you dream? No, or I don’t recall them. I’ve had a couple dreams but there was no visual or sensory component to them. When I woke up, I just knew a list of “plot points” about things that happened. This is also how I digest fiction.

Ah thanks, I missed this one when reading the article. Some other commenter talks about having a coworker with aphantasia but still being able to dream so they may well be a whole spectrum of what people can / cannot visualize.
