Subjective experiences seem mystical to us, because how could physics could cause something like this. One way to understand it is that we as experiencing subjects are made of nodes that can make things up and we have no choice but to believe them. Our nodes happen to produce useful, reliable things for us (except maybe when we are dreaming or on drugs) but the nature of the things they produce is different than what we believe, and have no choice but to believe. Like when we experience fear we are basically acting like we do driven by these signals, but it's all theatre. Useful theatre might I add, but it's just signals and how we interpret them. Vision is also just signals, there is just a lot of processing at the nodes so we get increasingly useful signals. We don't get a bunch of pixels, we get shapes, or better yet faces, intentions, predictions, stories.
The different parts of us do their jobs and a coherent picture is created. The most coherent picture is the first person view, but it is a fabrication. It's like a news report. The perceived self is a part of a stitched together story, not a central agent. The whole brain is the agent, however we only remember the story. The story is what ends up as a memory. The perceived self exist because I is an important context needed later for prediction, like the dimensions of your body and a lot more in a social environment. But your perceived self is not the actual you, just as your perceived world is not the actual world.
The general idea is that the signals from the nodes are processed and fed to the hippocampus to create an episodic memory engram, which reactivates the nodes that contributed the signals. This is when subjective experience happens, after all the work is done. Granted the next time the nodes can rely on what happened before, so we are not philosophical zombies, we don't passively experience it all, but the central agent is only a useful theatre, we are multitudes under the veneer.
