I keep forgetting to ask about this, but I remembered this time. Any time I close my eyes, if I focus on the edge of my vision, I am aware of - you guessed it - a pulsating ring of light. I'll describe as well as I can. Imagine a perfect circle, right at the edge of your most extreme peripheral vision. Sticking out from this circle are short, straight lines, almost like cactus spines, or rigid cilia - also white - and spaced sporadicaly. This ring, and its sixty or so spines, pulsate continuously. The whole circle turns a few degrees to one side and it expands ever so slightly, then jumps back to its original size and position. It oscilates thusly perhaps 6 - 7 times per second.

I don't know why, but I have a feeling this is something that everyone sees, but no one ever mentions. It's easiest to see in a dark setting, as you try to relax. Does anyone else know what I am talking about? Does any one know what it is? If you've never seen it, look for it. I bet you'll find it there, at the edge of sight behind closed eyes. It seems like it should be useful somehow, but I haven't figured out how yet. Any thoughts?
