Yes. It's called "Eigengrau" and it happens due to the adaptation of the eye amidst the darkness.

The indistinguishability of dark events from photon responses supports this explanation because rhodopsin is at the input of the transduction chain. On the other hand, processes such as the spontaneous release of neurotransmitters cannot be completely ruled out.

sbeak@sopuli.xyz · 11 pts · 283d (1 reply)

So it's like when a camera doesn't have enough light to properly take a photo, producing a lot of grain. Like when you have a high ISO when taking a photo/video in a dark room, it looks very grainy. I guess the eye is still adjusting its "exposure" if you see some of this graininess in the dark (or when you close your eyes?)

14th_cylon@lemmy.zip · 14 pts · 283d

the brain is always trying to find pattern in incomplete data. one of the explanations i have seen is that when our ancestors were sitting around the fire, those who saw the tiger or something lurking in the dark had better chance to pass their genes than those who didn't.

it is why we are seeing patterns in clouds and random geometrical shapes on walls and stuff like that.

You can also see them by holding a (not too bright) flashlight against your cheekbone and pointing the beam at your eye. The light needs to come from right below and you might need to move it around a little until you get the angle just right.

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).

Draegur@lemmy.zip · 6 pts · 283d (1 reply)

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!

rustydrd@sh.itjust.works · 2 pts · 283d

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.

I think it's called visual snow, and it's normal.

justastranger@sh.itjust.works · 9 pts · 283d

Seconding this. It's not incredibly common but it's not incredibly uncommon. Research shows that most people who have it don't notice it until it's pointed out. Drugs and stress tend to exacerbate the effect as well.

LwL@lemmy.world · 6 pts · 283d

Visual snow is when you see it with eyes open afaik. But yea, still not terribly abnormal on its own. Visual snow syndrome is a thing though, but it's more than just seeing an abnormal amount of visual snow (the normal amount seems to be when looking at unicolored surfaces and in dim light).

Mouselemming@sh.itjust.works · 21 pts · 283d

Yes, and if you GENTLY press on your eyelids you can make other colors happen.

Also if you stare at a clear sky, NOT AT THE SUN, or at a bluish wall, you may see little swirly things, it's the white blood cells in your retinas swimming around.

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

/Obviously I'm not serious....

tree_frog_and_rain@lemmy.world · 1 pts · 282d (2 replies)

But you're right.

Only the hologram is produced by the nervous system. Not God's super computer or whatever.

Adderbox76@lemmy.ca · 1 pts · 282d (1 reply)

I mean, I guess that's true in a peculirar sort of way in which nothing really exists outside of our perception of it.

What I mean by that is that whatever we see, hear, taste, etc... is merely neurons firing in our brain, processing a signal that it receives. So if we're looking at a tree for example; that tree is just light/energy waves vibrating on a specific frequency. It's only when it hits our optic nerve and travels to our brain that it's translating into something that we call a "tree".

So when the eyes are closed, the random interference pattern could indeed be interpreted as you say. Goog catch. Kind of makes you wonder.

tree_frog_and_rain@lemmy.world · 1 pts · 282d

Yeah there's a term for it in Hinduism, Maya.

I've also spent a lot of time and study with Buddhism. Explored a lot of mind altering drugs.

Perception is a map of the territory influenced by karma (evolution and personal experience) In constant feedback with the territory, of course.

But the map edits itself out. Because when a tiger appears on the map we need to run, not debate rather or not there's really a tiger.

XeroxCool@lemmy.world · 2 pts · 282d

It happens to me at night because not only does it have to be quite dark, I audio need to be dork dark adapted. Your pupil is part of your dark adaption and widens in a mater of seconds. However, your receptors also get doped with rhodopsin, which takes up to 20 minutes to full replenish (blue/uv light bleachers rhodopsin). It's like being able to lower the F-stop on a camera like normal, but taking 20 minutes to raise the ISO

shirro@aussie.zone · 3 pts · 283d

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.

DeathByBigSad@sh.itjust.works · 3 pts · 283d

Yes, but its not purple, its just like as if your soul was drifting through the universe and you see tiny dot-sized stars from afar.

Sometimes I couldn't sleep and the lights are off and there is a tiny bit of ambient light outside, and I just open my eyes and stare at the ceiling and also notice a sort of static like that, but with a brighter background light.

MehBlah@lemmy.world · 2 pts · 283d

Mine varies from the static to a fine lattice grid that is constantly changing.

angrystego@lemmy.world · 2 pts · 283d

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!

Tollana1234567@lemmy.today · 1 pts · 283d

a small proportion of people have this, i have it mildly as well. my opthamologist at the time said it wasnt common and he only knew a teen that had it. its mostly because of the part of yuor brain thats active. its a wierd neurological thing. i suspect mines was due to diphenhydramine at the time, plus i had undaignosed spinal issue which would cause neurological/neuropathy in my limbs. i think the DPH made it more pronounced, as bringing it from the background.
