i mean everyone's mind builds a convincing internal simulation of reality and it's so good that most people think they're directly experiencing reality.

So what happens to someone suffering a psychotic episode, their reality gets distorted? But what reality though if it’s all an internal simulation? I think there’s partly an internal simulation to some aspect of reality but there’s a lot more to it.

The world model is not the world. It's the old map and territory thing.

Buddhist insight meditation actually proves that’s not true, fwiw.
