Not sure why you are downvoted. Well it probably doesnt require meditation because split attention is somewhat common here. My mother can follow multiple discussions like have a phone conversation and understand what I tell her. In general I can't.

So a bit harder for me. I can focus on work and follow some podcasts but not speak and at the same time listen to a full parallel convo.

I do believe brain to brain communication exists from experience too. People will be quick to call it schizophrenia and indeed it can be maddening because it evidently reuses your neurotransmitters for information propagation. That includes dopamine and can lead to the same issues some diagnosed people have, but actually a couple at the same time.

Without visual hallucinations but the brain gets a bit taken still, since it has to share processing. So it can induce adhd like symptoms, loss of phantasia, nucleus acumbens becoming nucleus incumbered :D, impaired motivation, etc.. But it is transient and you can argue it within yourself with some amount of relief. If you notice and start a loop of wondering where it comes from you are toast though.

Anyway, probably saying too much. You have to experience it. Probably someone playing with AI and neurochemistry. Still can't figure out the actual transport system. It does not make much sense from a wavelength point of view. Even if merely HF acoustic waves (since they can be more directed) not quite sure. Should ask whoever big galaxy brain created the havana effect... \sarcasm

At the same time people already know publicly how to decode brain signals and turn them into movements and Computer Interface actions. So the brain is not a complete blackbox. Some people might be further along...

Anyway... we will know eventually what is this all about..
