The idea that there is a conflict of prediction vs. reality, and a simple failure to connect disparate sensations into a whole are nothing alike. The former is a characteristic of something like motion or VR sickness; your body expects one thing, but receives conflicting information. Integration failure doesn’t require prediction, just different sensations not creating a whole impression.

The author describes experiencing hunger as a bunch of disconnected sensations, that don’t add up to one thing. She feels pain in her stomach, irritability, tiredness, but doesn’t integrate that into “I’m hungry” and just experiences them as different incidental feelings indicative of nothing in particular.

"Making predictions" sounds too broad. Everything humans do is basically pattern matching and prediction making.

It's the difference between knowing you're hungry and knowing you will be hungry. I can tell you that if I drive a car far enough it will eventually run out of gas, so I should probably go to the gas station before a big trip. But that's a very different problem from having a gas gauge that's broken entirely.
