I think it's worth taking the results seriously but not the proposed mechanism literally. Equating an internal feeling which is loosely referred to as a form of "energy" with physical electricity/bioelectricity would be a mistake. Of course all sensations are indirectly the result of nerve impulses and bioelectricity, but you wouldn't say that someone experiencing tingles of say ASMR has literally received "energy".
It may turn out that you can consciously influence bioelectricity on certain levels (I mean you can certainly control motor functions, maybe you can modulate the current of injury [1] by thinking about a body part?). But you need to be clear about the level of abstraction: when you feel a pit in your stomach are you going to literally attribute this to "clogged energy in your lower dantian", at the chemical level of increased norepinephrine and reduced blood flow to your stomach, or simply as a result of your emotions and anxieties at the moment?
A less fanciful way to say "experience deeper aspects of oneself, one part of which is a greater sensitivity to energy movements and corresponding fields" might simply be "greater sensitivity to emotion and bodily awareness". People do the same thing with therapy, discovering emotional/mental baggage they'd been carrying for a long time, and parts of the body they had been unconsciously tensing.
When everything in our body is meditated by impulses and electricity, saying that you're "becoming more attuned to energy" can be technically true but a functionally useless abstraction. You can equally say "more attuned to chemical fluctuations in your brain/body" or "more attuned to homeostasis disruptions". Maybe in the past they didn't have the vocabulary to distinguish these levels of abstraction, but today we do. (And Michael Levin's work is showing that we've actually been underpaying attention to the bioelectric). This is the same way that the "theory of humors" sort of makes sense on a metaphorical level but it falls apart in a literal sense.

Yes, agreed. There has been plenty of einstein-smart humans making observations for the ~30000 years of human prehistory, with and without the scientific method. Even with a low hit ratio, there is bound to be plenty of correct intuitions. A large number of post-renaissance scientific discoveries are about expressing these in the right testable framework and language.
Unfortunately, people do not bother to make the effort to study these (first hand sources, historical documents like travelogues, even scripture) and rely on either making up or repeating random shit.
