In a darkened room, or with your eyes closed, you may have experienced the noise of closed-eye vision. The phenomenon of closed-eye hallucinations, or a phosphene, is the perceived sensation of seeing light, when no light is actually entering the eye.
There is form in the indistinguishability of dark events.
Even in the absence of light, some impulses are still sent along the optic nerve, causing the sensation of an animated, dark coloured noise.
