Of note, 200-1,000 nm overlaps with the wavelengths we perceive.
Could it be that under some particularly dark environments, some particularly sensitive humans (or animals) can get a glimpse of it? I believe it's quite plausible.
Are you suggesting this light is of lower intensity than what a single photon puts out? Explain your reasoning.
It's pretty easy to see the layer closest to the body. It's kind of like a bright outline about 1cm thick.
The layer with colours is further out and I've only ever seen it once. It was rad though, 10cm apple green flames appearing to shoot off my body as I moved my eyes around.
Certain lighting conditions make it easier, eg slightly dark environment with a backlit subject.
Anyway cue the downvotes from the overly analytical people here. As with all things meditation, the more you try the less you'll experience.
One way to study this is to shut off the neural channels for external stimuli with NMDA-antagonists or isolating the entire body, you'll experience immersive perceptions, including visions. Falling for various degrees of decoration your brain provides spontaneously or has been trained to provide is foundational to many religious and mystical currents throughout history. Some of them consider not falling for at least some of these things to be the basic exercise of their regimes, e.g. non-reaction to mental phenomena in Goenka's vipassana or time-locked prayer as in canonical hours and islamic prayer.

This breaks these guidelines:
Please don't fulminate. Please don't sneer, including at the rest of the community.
Eschew flamebait. Avoid generic tangents. Omit internet tropes.
Please don't comment about the voting on comments. It never does any good, and it makes boring reading.
I know it can be upsetting to face hostility when sharing experiences and concepts that are deeply meaningful to you, but let's try and avoid taunting people like this. When it's predictable that a comment will attract downvotes, it's an indication that there might be a better way to express things.
Be kind. Don't be snarky. Converse curiously; don't cross-examine. Edit out swipes.
I have always been interested that we cannot see infrared, but some reptiles can, we cannot because our eyeballs are flooded with warm blood, there is no way for our bodies to distinguish signal from noise.
This made me think of the scrotums purpose to maintain the testes slightly below body temperature, which then amused me with the idea that it might therefore be able to function as a kind of infra red, body light retina.
so I was mocking some primal hunter ideas, but certainly no one posting on this page
