Hmm this leads me to recall a bunch of ancient pseudoscientific sounding beliefs and see whether or not they might be plausibly explained by this mechanism:

* Is it possible for humans to get a vague impression of other humans' thoughts via this mechanism? Not via body language, but "telepathy" (it'd obviously only work over very short ranges). If it is possible, maybe it is what some people supposedly feel as "auras"

* Some animals have a preference for sleeping direction in alignment with magnetic pole, are some sleeping directions "healthier" than others for humans?

That aside, I didn't follow the part about how this is an answer to the hard problem of consciousness. Why couldn't the brain achieve global summarization via another mechanism, and why does having this "global summarization" result in qualia?

For what it's worth, I have a disorder that causes me to see "auras" around people quite often. The nature of the disorder is that my brain can't filter out its own sensory noise properly, giving rise to a lot of visual artefacts that non-disordered brains filter out. These range from 'TV static' to stuff that's not a million miles away from diffusion model artefacts, but the auras around people I see pretty much all the time especially against plain backgrounds. It's not very well-known or studied but fMRI studies have recently implicated the same serotonin receptor psychedelics target, and it's also linked to migraine.

I think this disorder being more prevalent than expected would be a good explanation for auras. It was once thought to be very rare, but many people who have it aren't actually affected enough to seek out a diagnosis. It wouldn't be an unreasonable source for images like auras, saints' haloes, and other things like that since they're just an ordinary part of vision for me. I also think it somewhat vindicates Aldous Huxley's thoughts on the subject.

I really like the idea of electrical fields being somehow important for consciousness, and it's not something I'd rule out off the bat. I just think that disorders of perception are a better explanation for auras and similar phenomena.

If any of it was possible, it would be easily scientifically provable by very simple experiments. The fact that it hasn't been proven while people would have very high motivations to prove it, suggests it's very probably not happening.

I've always held two complementary beliefs regarding auras and similar senses:

1. It's plausible that some humans can sense subtle information about things like emotional states or reactions in other humans using non standard sensing mechanisms (so maybe electric fields rather than sight, for example).

2. I'm very certain that for overwhelmingly most humans who claim they can see auras, it's one of: bullshit, fakery, self delusion, wishful thinking, charlatanism, a scam.
