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.

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.

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.
