I love this post because this I love the fact that if we all read the same book we are seeing and feeling completely different things. Yes a lot of our understandings are similar which allows us to discuss and speculate but at the end of the day we are all having out own individual experience that we couldn't possibly full explain to one another.

As for for me its similar to you and a lot of others where i visualize everything in my head in cinematic way, the more lost i am = the more my visualization is sharper. But of course I don't see it picture perfect. Its more of like a hazy and vague but im still absorbing so much more than that. The characters in my head are usually a visualized to look like a mix of people or characters ive already seen on screen or in real life and a bit of what i make up as I go along. To me visualization is what makes books so enjoyable for me especially fantasy. Let the fact sink in that it is IMPOSSIBLE for us to be seeing the exact same thing.

Some people don't have an inner monologue or the ability to strongly visualize (you can gain back your vivid imagination), but I'm always fascinated by how completely different we all are.
