I have apahantasia and one thing I don't quite understand is how people without it visualize when their eyes are not closed. If you are thinking of something, maybe listening to an audiobook while driving, does the imagery in your head still show up? Or are their like two modes, eyes open and eyes closed?

Because I don't see anything either way, there is no change. How does imagry and imagination work for you without apahantasia, when your eyes are open?
