..The only time I've ever hallucinated was....oh, last monthish when I was desprately afraid of my dreams, and stayed up for 72 hours at a stretch. That was....fun utterly fucking terrifying
Yeah, the visual snow thing was actually pretty terrifying for a long damn time. I couldn't sleep in the dark until my mid-teens, because there were giant multicolored amoebas floating in the room, presumably waiting to eat me. Lights back on please! With light, it's more of a multicolored buzz if you're not paying specific attention to it.
So i'm not the only one. You got any idea what causes that?
They've got no flipping idea, currently. May be genetic, may be onset, may be any dozen of things. May be several different things with similar symptoms. There's generally no major pattern (though there's several minor ones, especially among onset cases) among people with the condition. There's a general potential link with depression, but nothing definite. Me, near as I can tell it's genetic. Have had it since birth (or at least as far back as I can remember, so around early 3-ish), father reported the same thing and that his father had it, so... yeah.
Most I've picked up that's definite is that it's almost certainly neurological and not anything to do with the structure of the eye. So it's your brain gone funky, not your peepers.
I had to deal with stuff like that. Only it wasn't amoebas, it was bubbles and geometric shapes and it was awesome.
Yeah, it's those too, it just took me a while to stop being terrified and notice 'em
