I used to be a visualizer. At around the age of 8-12 I could imagine a movie in my mind as I read. Once I read an entire 500 page book, one which was relatively high level for and 8 year old, in a single day. Unfortunantly, I don’t to do that anymore despite being an older, more experienced reader. I slowly push the pages and subvocalize. it takes me a few weeks to read 500 pages. I don’t know what changed my mindset. It’s a lot less satisfying to read this way. Does anyone have tips about how to active a mental movie while reading?
What are you trying to read?
Most children books are deliberately written in a way that’s easy for them to visualise, whereas a lot of adult books don’t prioritise reading level. Also there’s much more variety in writing styles and difficulty in adult books. And as adult readers how you read as an individual changes. Maybe you just need to find authors/books more suited to you.
