Thank you for this.
You're not the first person to say this. I have some empathy for this view, even though its the opposite of mine.
For me, audiobooks offer, more space for imagination. More recently its also a more consistent way to get unbroken narrative into my head. However I strongly suspect that is down to how I process information.
I didn't really read properly until I was quite old, however talking radio was quite ubiquitous in my house. There were lots of audiobook-like content. so perhaps its training?
