brain spooks thread.

I can see at a microscopic level

Have you ingested any psychoactive substance?

>>17724435
nope, never have.
cant say im not interested in it though.

iv been like this since childhood.

>>17724435
but i do agree, it does sound like my brain is doing something "normal people" would see after a very light dose of psychoactives.

>>17724424
me too

>>17724381
i get this too

>>17724472
neat, cool too see im not the only one, though i never expected that to be the case.

shamefull self bump, i kinda want to hear some stories from people before this dies.

heres is a spoop image from a unrelated thread earlier.

desu brain spooks are kinda lame and minimally spooky.

I get tactile hallucinations. Sometimes a web or rope closes around my arm and squeezes, sometimes my hand is wet and then I look and there's no liquid. A lot of the time there are long hairs that end up being responsible, but half the time I can't find any hairs.

>>17724587
makes you wonder about how the brain works though, doesn't it?

Here op I got one.
Sometimes if I stare for no reason at a wall I get this pattern at my focal point and it switches between pic related
I can make it last as long as I want and I can make it go away by either focusing or directing attention to something else. It's like TV static but all the static is the pattern in the picture

Look up HPPD (Hallucinogenic persisting perceptive disorder)
What you're describing is exactly how this feels for me. You may not exactly have this, but I do, and what you described sounds exactly like it. It's non-intrusive, and pretty chill. Don't worry about it, meditate more often and you can begin to manipulate it to a degree.

>>17724627
oh yeah, that reminds me shadows and darkness have TV static to me too.

>>17724634
manipulate, like how meditation gives you more control of the subconscious?

but that eye, thats some cryptic shit, do you think there is other reasons that coincidence of facination with the eye symbol that is the reason it make an appearance?

i know the eye visualization is a pretty common thing in "altered states of consciousness"

goofy term, i just like how it sounds.

>>17724737
reasons (than) coincidence.

im a fockin spastic

>>17724381
Hey OP,

Get to the doctor immediately this is most likely due to a braintumor pushing on either optical nerve or on the back of your head. Be safe brother

>>17724737
Man I don't know what the fuck it is. But I've been able to do it since I was coherent. I've never worried about it. It's honestly a late-night-no-sleep stare at the wall and make it do the thing for fun kinda thing

>>17724746
id rather die than listen to you, fag enabler.

>>17724749
yeah same, i have to really kind of force it, almost loose myself in what im staring at, to get this to happen, so yeah definetly a massive tumor causing this, or maybe aids.

>>17724746
jk im actually going to check this out, kind of interesting.

!!!!!

:D

I can see a pattern at the focus point too!
Most of the time it's "hidden", sometimes it appear, under the right conditions you can pick it up voluntarily and dismiss it voluntarily too, other times it'll kind of get into a loop, become obnoxious and won't hid again until you naturally forget about it.

I earnestly believe we're perceiving some cell pattern(s?) within the fovea centralis, the ultra-HD center of the retina.

The pattern is very slightly irregular, frayes out at the outside, lacks defined edges, and is constantly shifting in hue in a very "flighty" way - dare I to speculate because of optic pigments depleting and renewing.

This looks a very finely-textured glaze on whatever you're looking at, easier to pick up against uniform surfaces of a single color.

I don't have any explicit reasons for the colors I picked, just what felt more natural. It's obviously more blended and subtle than the image.

Further thoughts:
-Is this a *direct* perception of the retinal cells in the fovea, or from farther inside the visual pipeline?
-Does this pattern vary among people? (resolution varies, I'm wondering about the specific pattern)
-Can everybody see it but most just don't notice?
-If not everybody can see it, why are we able to?

>>17724746
read a little bit, you where probably joking.
it says its non cancerous and its common children that children get it. and usually it doesn't grow after that.

meh, pretty spoopy. so i guess its fitting for this thread.

>>17724779
Yeah Nigga that's the pattern yo. Thanks for drawing that. I saved it so I can use it as reference.

>>17724839

You're welcome :3

When i stare at people i can see the shape of their body with a red out line. Some peoples outline aren't there while other peoples can be higher out of their body or not as high.

Though it's kind of hard to explain, visual snow is often described as an additional layer of clear/green/purple/red/yellow "noise" applied over the afflicted's field of view, like a grainy old TV program.

It may come with other effects such as photophobia (an intolerance to bright lights due to hypersensitivity), negative afterimagery fucking UP THE ASS, a greater degree of positive afterimagery (may be more hallucinatory in nature if they persist longer than a second), tinnitus, and enhanced blue field entoptic phenomena (AKA "sky sprites").

It seems to be associated with ASDs (not exclusively though you're probably autistic if you're on this board anyway) and hypermetabolism in a certain part of the brain involved in sensory processing https://en.wikipedia.org/wiki/Lingual_gyrus (I'm no neurologist lol)

Persisting visual snow can feature as a leading addition to a migraine complication called persistent aura without infarction,[4] commonly referred to as persistent migraine aura (PMA). It is important to keep in mind that there exist many clinical sub-forms of migraine where headache may be absent and where the migraine aura may not take the typical form of the zigzagged fortification spectrum, but manifests with a large variety of focal neurological symptoms.

This sounds spoppy.......but cool !!!

>>17725137
Persistent migraine aura without infarction (PAWOI) is a little-known condition first described under the designation prolonged migraine aura status [1] that is not yet fully understood. PAWOI is said to be a possible cause of a variety of neurological symptoms, including visual snow, loss of vision, increased afterimages, tinnitus, and others.[2] However the pathogenesis of PAWOI is unknown, in other words, it is not known exactly how the aforementioned symptoms are caused. Furthermore, it is not clear which medical examinations are useful in diagnosing PAWOI. At present, PAWOI is usually diagnosed solely based on the patient's present and past symptoms. It may be possible that an overactive brain or a chemical imbalance is partly to blame for the disorder. Different medication has been tried as treatment, notably acetazolamide,[3] valproate,[4] lamotrigine,[5] topiramate, and furosemide.[6]

You know a lot,

>>17725226
Could be.

You need an electroencephalogram, but is visual snow if it looks like this gif>>17725220

The pattern is very specific, most probably a problem in the visual cortex, any physical trauma to the back of the head?

>>17725244
wasn't asking for a diagnosis, I was just reposting one of my threads

if it's little-known, I'd guess I don't have it anyway.

Sorry about that.

This weird pathologies is how they classified, all kind of paranormal phenomenons.

Scientific theories, some not even that, just mere descriptions of a phenomena observed.

Witnesses, not wanting to say the truth for fear of jeopardice their jobs.

>>17725137

Dude, thanks. I have a TON of that shit.

Have had visual snow all the time since forever. I just see like that. All the fucking time. Always.

Blue field very common too.

Scintillating Scotoma very occasionally. Scared the shit out of me. Thanks. Now it won't.

Still, the freaking "biological crosshairs" phenomenon is not described in there, or if it's in a link within there, I haven't caught it. If it's part of visual snow, it's a very particular part of it, because it's stable, permanent, and coincides with a functional part of the visual field. If visual snow is post-eyeball and neurological, the phenomenon I described can be too, but it just _screams_ STRUCTURAL DIFFERENCE. So if it's neurological in nature and related to visual snow, it must be the visual snow that corresponds to a particular sub-feature of the brain.

I've examined the little thing for HOURS, because I used to do swimming and the diffuse blue light inside a swimming pool is the #2 perfect background for examining this shit - #1 being clear sky.

Also, snow is always present everywhere all the time, the "crosshairs" can be voluntarily brought up and hid to a great extent.

I also "enjoy" other visual anomalies, such as:

-deep, bright blue lights flaring out quite a bit (is this normal?)
-very bright objects against a dark background creating a "smeared up" secondary image (this might be vertical focus astigmatism... but it's not exactly quite like depictions I've seen...)
-Squiggly trollish lines fucking with me if there's a horizontally-striped object at certain distances.

-if half-asleep and sudden noise, I see a burst of static too.


OTOH, it totally looks like I have persistent migraine aura since I also have chronic/recurrent depersonalization. Very few times have I had really hardcore headaches... but a couple of times my head has been aching for a fucking entire week. Bearable headaches very common, I attribute them to bad habits.

*reads scientific articles*

>>17725270
The flashes could be photopsia.

Photopsia is the presence of perceived flashes of light. It is most commonly associated with posterior vitreous detachment, migraine with aura, migraine aura without headache, retinal break or detachment, occipital lobe infarction, and sensory deprivation (ophthalmopathic hallucinations). Vitreous shrinkage or liquefaction, which are the most common causes of photopsia, cause a pull in vitreoretinal attachments, irritating the retina and causing it to discharge electrical impulses. These impulses are interpreted by the brain as 'flashes'.

This condition has also been identified as a common initial symptom of Punctate inner choroiditis (PIC), a rare retinal autoimmune disease believed to be caused by the immune system mistakenly attacking and destroying the retina. During pregnancy, new-onset photopsia is concerning for severe preeclampsia.

Photopsia can present as retinal detachment when examined by an optometrist or ophthalmologist. However, it can also be a sign of Uveal melanoma. This condition is extremely rare (5-7 per 1 million people will be affected, typically fair-skinned, blue-eyed northern Europeans). Photopsia should be investigated immediately.

It fucking should.

>>17725299

What flashes.

>>17725270
could you expand on the biological crosshairs? sorry if you mentioned it earlier in this thread
as for those last two points, I'm guessing:

-Squiggly trollish lines fucking with me if there's a horizontally-striped object at certain distances.
Common mirage, can also be observed over roads while driving. More of a light trick than a hallucination. Seems a little like an effect I know where there's a slight magnifying field around objects (best being the tip of a fingernail, if it's long enough)

>-if half-asleep and sudden noise, I see a burst of static too.
I think that one's called "exploding head syndrome"

>>17725302
>deep, bright blue lights flaring out quite a bit (is this normal?)

>>17725270
>>17725303
actually bothered looking it up- exploding head syndromes auditory, whoops

>-deep, bright blue lights flaring out quite a bit (is this normal?)

like, around objects? think that's particularly bad negative afterimagery, sometimes just because, mostly because you've stared at it for too long

I guess that "burst of static" thing's just you refocusing your eyes quickly, and seeing visual snow again

>>17725309

Blue light defects:

I meant when I'm looking at an actual bright, deep blue light. Emitted light from an object. Like neon signs.

It just gets everywhere outside it's contour in a weird way. It's not flashes. It's just the light bleeding off of the shape of the object.

I'm pretty damn sure it only occurs with a certain wavelength range/mix, or at least only within that range/mix does it occur to a significant degree.

It's deep blue lights, removed from cyan, getting closer to purple but not quite. Cold purples can do it a bit but not as much.

"crosshairs"

>>17724779
Pic related.

It's an extremely small pattern, about the same visual field footprint ad my pinky nail at full arm's length (which is only a subjective measuring but I don't know how to estimate degrees or mintues in vision. My hands are small.). The pattern is static but the shapes change in hue with the same kind of very quick (but smooth) rhythm as visual snow. It's more easily perceptible under the same conditions that make perception of visual snow easy.

Look, if I can come up with some way of animating a simulation of it, I'll just make a "foveal pattern animation" thread here in /x/, the static pic doesnt really convey the thing (except what does the pattern geometrically look that)

Squiggly lines:

Squiggly lines got jack squat to do with mirages. I know what a mirage looks like, this is nothing of the sort. It used to see it a lot on one of #1 flatmate's t-shirts. A lot because we would eat at the same table, and when I was looking at food on my fork, he and his t-shirt were under just the right conditions.

It's not anything like a mirage, it's totally "my brain is crapping out on this area and just slaps something together", blindspot or scotoma stile but not as hard and in movement.

storefront

>>17725311

I looked it up too. Exploding head might have happened like, twice.

Burst of static:

The burst of static thing is with actual noises. I'm half asleep, eyes closed, someone opens the door; or the TV makes a loud noise, if my vision is in "seeing nothing" mode and I *hear* (actually hear, from an objective, measurable source) a startling noise, I see static along with hearing the noise.

If visual snow is constant static, by contrast, this burst of static is:

- Much coarser-grained
- Much higher-contrast. Can reach almost black-to white.
- Completely fills the (empty) background, instead of "thinly overlaying on it"
- Is continuous in time with visual snow. Normal visual snow grain, if perceived before the noise, sharply grows in grain size along with the intensity of the noise up to a certain maximum grain size, moving more quickly and jarringly, in a sort of "scrambling" movement, then return to or evolve into normal visual snow static.

I don't think my eyes have time to refocus or anything to refocus on BEFORE this happens.
