Contextual discernment
How do I discern spiritual warfare when I dream of book?
This angle exists only in the biblical reading. Here is the general reading of book, with no religious reference.
General reading
Set aside any religious reading, and a book in a dream generally represents knowledge, memory, or a story about yourself that's still being written. An open book often shows up when you're piecing together an understanding of a situation, sometimes for the first time. A closed or locked book usually reflects a truth you're not ready to face — about a relationship, a decision, or your own past. Writing in a book yourself often mirrors a real sense of agency returning, the feeling that you get to decide what happens next rather than just react to it. The useful question is not 'what is written for me' but: what chapter of my own story am I currently avoiding rereading?
