Your brain is also a predictive model to an extent, it receives input such as visual or sensory and predict what will happen for example visually and produce outputs such as actions and thoughts. You realise most of the things we see daily are more memories than photons, most people don’t know that and think we only see with our eyes, while in truth its the eye that triggers sight and then the memory takes over to reduce the brain computation. In other words we all are hallucinating reality.
