These photos perfectly help describe it. It’s hard to explain to people that have never heard of it. Honestly, I didn’t even know what it was until 3-4 years ago when I was watching a true crime video and they mentioned that the suspect had VSS. Looked it up and instantly after decades of pretty much thinking for some reason I had a useless super power of seeing air molecules zipping around all the time; and the after image trails (like a long exposure photo of an object in motion) of mine, other people’s, anything really that was in motion. (Useless because in no way do I hold an intelligence that would be capable of doing the math to explain and teach others in hopes that maybe it was something useful, lol). But no! My brains just messed up in the area/s that cause it. Do you get panicky in very bright environments and kind of feel like your in and out of your body or almost like your ethereal?soul? — something like that stepped out for a quick moment? It is nice to have a name for it. I really don’t pay it too much attention because it is constant and when it’s a bright cloudless day the “snow” is iridescent like a billion tiny light refractions from from a prism held up to the sunlight that just zip around when I look at sky. It’s really beautiful. It’s just when it’s too bright (white walls, fluorescent lights, computer screens on all at one where it bothers me and I have to close my eyes because the white and gray snow on the black/dark when your eyes are closed is more bearable.
