    Purple, green, pinks and oranges (that’s the blood in my eyelids I think). If I rub my eyes, the pixellated screensavers get wild, which I think means you’re not supposed to do that.

    It is hard to know exactly what we see because our brain processes it so much and then we have to put it into words and we could easily be describing different experiences the same way or same experiences differently.

    I would guess any light receptor produces noise whether that is a few stray protons or just thermal chemical/electrical processes. I would think for most people the brain is receiving noise very much like this but how they experience it depends on how it is processed. Unless there is some after image from recently staring at something bright, when my eyes are shut my brain gives me an impression of nothing which is almost certainly not what my retina is detecting.

    What you’re seeing is the inner workings of the holographic universe we inhabit. Your brain interprets the signal as static.

    Yes, it’s random firings of light receptors from the absolute ocean of potential stimulators for such sensitive cells and sensitive neurons that connect them to your brain.

    Your brain does a profoundly involved job at every moment editing your visual input into a coherent, moving picture, but your brain edits out a LOT of interference and noise every moment.

    If you really wanna blow your mind and prove it, make a pinhole in a card and in a dark room and look towards a light source. If you wiggle the pinhole light beam across your retina you will suddenly see all the blood vessels that feed your retina. Evolution decided it would put them on the front for some reason, but your brain normally makes it literally disappear for you. When you wiggle the shadows of the vessels, your brain forgets how to edit it and they appear like a mass of floater-spaghetti.

    Edit: you can suddenly see your nose. You’re welcome.

    Yes. And if you want to see something really cool, take a look at a clear blue sky. You’ll notice tiny dots of lighter color moving quickly following constant short trajectories. These are your own leucocytes moving through the capilars right in front of your retina. The brain compensates the darker color of the predominant red blood cells, so you can’t see the capilars, but the white blood cells are translucent, so they appear as lighter dots!

    This is just the result of neurons firing and chemical reactions taking place, and it’s normal. Personally, for me it depends on my state of mind when I try to sleep. When agitated, I see noise like in your picture. When calm, I see flat, colorful shapes with soft edges that float around and change shape more or less rapidly (kind of like a lava lamp).

      Ohhh yeahhhh the lava lamp like ones are cool. Sometimes vague impressions of cyan and red, sometimes propagating in waves. I’m so glad other people are describing it!

        I also find them really helpful for falling asleep. Sometimes when I feel stressed and see mostly noise, I’ll try to spot the color shapes and focus on them. It’s kind of meditative and helps me fall asleep faster.

      Mine can vary wildly depending on what kind and the quantity of psychoactive substance I’ve taken.

    Yes. I “see” it too but can unsee it quite easily. I think it’s more apparent in unlit environments.

        Hm okay. I’ll check again in six months when Belgium isn’t a depressing film Noir scene straight from Max Payne 1 & 2.

    I see a little “DVD” logo zipping around that changes colour when it bounces off the periphery of my vision.
