Even people with aphantasia see as a result of a combination of bottom-up and top-down processing.

Also note that aphantasia is not a condition which is confirmed to even exist.

As an aphant I’m pretty sure it exists. But just in case let me close my eyes and double-check...nope still nothing there. ;-).

I'm pretty sure that you either see the same thing as I do when you close your eyes, or you don't, and that it's very difficult to communicate about what "seeing" something in your mind actually means.
