That's a really interesting scientific finding. From a personal experience, once I closed my eyes and actually observed this phenomenon. I could observe many spherical waves of light each pulsating, and not only that but I could feel the effect of each wave viscerally. It definitely felt healing. I wasn't sure what this was, was it the vibes of meditators around the world? Maybe this research finding is what I was observing.

Reflexively, that doesn't make sense. I cannot imagine perceiving ionic CSF flow with my eyes.

But thinking about it more, maybe there is something to it? I'm wholly unqualified to speculate here, but I know computers and computers are exactly the same as everything in the real world, so let's go! ...

- When restful and with my eyes closed, I definitely "see" waves move across my field of vision. My eyes see "black" (or dark gray) with slightly lighter edges that move and act like a wavefront in a fluid. There's distinct flow, and (minor) swirling and interference. I've seen these since I was very young, and I have no idea if it's a common thing or if it has a name. It must. I've mentioned it to a very small number of other non-experts but no one has ever recognized it. (I also sometimes see tiny colored tiles that light up in moving masses -- again rarely mentioned but never recognized, probably an unrelated phenomenon...)

- I do not think these are simply phosphenes, because there is no external proximate stimuli. Though I suppose we all live in environments saturated with EMF, most of the time, and a proper test would require being in a very remote area (and that's probably not enough). Though if I can "see" the presence of EMF, I'm totally making some phone calls to Charles Xavier's people.

- I've theorized that this was fluid in my eye (eyelid is too thin) moving around and refracting what little light is getting through in a dark room. But it also happens when I am completely still (though nothing in the body is ever completely still), and it also happens in complete darkness.

- The "shape" of the waves does not resemble anything that could be related to blood vessels in the eyelid. And again, complete darkness.

- So, is it possible that it's actually this ionic flow of CSF through the vision-sensing part of the brain? Not actually light coming through my eyeballs at all, but fluidlike electrical variations in the parts of the brain itself which are sensitive to the electrical signals normally coming from the optic nerves?

I have no idea. But it's an fun new angle to consider in the idle moments while I watch the waves flow before I fall asleep.

(That said, please feel free to correct my wild speculation if there's an obvious explanation that has not intersected my completely-unrelated fields of study! :)

I deliberately didn't use the word "see" when phrasing my response. I used the word observed because it was an observation, not a seeing. And I'm not describing a flow of vague amorphous whitish material, I know what you're talking about and I'm not describing that.

I tried to observe the phenomena yesterday again and couldn't observe it but it was very specifically this in the past: spherical orbs of white light expanding from a centre. There were many of these, and my perception was that the nature of this geometric expanding shape was healing. To describe it more clearly, many years ago I felt that the perfect geometric spherical nature of these expanding waves were designed to gently round off rough edges. To make an analogy, imagine kneading some play dough over and over again. When you use your hands to do so, every time your hands make contact with the play dough, the play dough changes shape slightly because of the contact between your hands and the play dough and it gets softer. Now apply this concept to the idea of energetic waves making contact and passing through the material substrate of the brain and the rest of the body (yes I observed the waves applying to more than just my mind). It was my physical and conscious perception that as the spherical waves emanated from some center, they gently readjusted the physical substrate that they passed through. And because there were so many of them in different spatial locations, this readjustment was incredibly refined.

I was slightly disappointed to see my comment down voted but I'm not too surprised. I stand by my description as an accurate and well considered, rational description of what I had observed in the past.

[quesera]

I didn't mean to put you on the defensive. I used the word "perceive" in response to your comment, and only used "see" for the description of my personal observations.

I didn't downvote it, but I wasn't sure I understood your first comment. Others might have also been confused.

Anyway, it's all fascinating to me. I am inadequately schooled to know what is a novel observation, but when I hear experts talk the common theme is how little we really understand about the brain. Obviously, my "little" and their "little" are very different things.

[theaussiestew]

No problem, you didn't put me on the defensive, I was making the down vote comment in general, not to you.

Ok, I have never told anyone this, but I also sometimes wake up and “see” like a waterfall effect over my vision. It only happens very rarely and only for less than a minute after I get woken from a deep sleep. It is not unlike a moving sensation or water moving over my eyes. I realized that it is probably fluid moving over my visual cortex and being interpreted as vision. Seems weird and I have nothing to back it up on, but it has happened multiple times over my lifetime and the sensation is exactly the same every time.

[quesera]

I may have seen that as well -- is it vaguely like the visual noise you see when coming out of anaesthesia or after having passed out?

I've always assumed it is caused by ~"static in the visual cortex", while your interpreter "syncs up" / "tunes in" to the usual signal.

I'm sure that's another tortured computation/communication analogy, but it's all I got.

[theaussiestew]

I'm not talking about the vague flow of amorphous material, I can perceive that too but it's not what I'm referring to. I made a follow up reply where I describe specifically what this phenomena is and my hypothesis on the mechanism behind the healing.

[nprateem]

Perhaps it's how meditation balances the sympathetic and parasympathetic nervous systems. But yeah, I know when my mediation is deepening because the rhythmic pulsation up my spine into my base brain begins.

[theaussiestew]

I'm not talking about the general effect of meditation which is to relax the body and increase the flow throughout the body. I was talking very specifically about this concept of spherical expanding waves of light. To make an analogy, it resembles a moderately white light expanding from a centre. See my other comment where I describe how such a phenomena could be healing and restorative using a physical analogy.

[dynisor]

Are you perhaps describing phosphenes?

[theaussiestew]

No I'm not. Please see my other comment where I make a physical analogy to why spherical expanding waves of light may be healing and restorative.
