makes you think you've had too much giggle juice

yeah, it moves when I look at it and then I move my eyes to the side and it stays still for a bit and then the other side moves ehehehehehe

[StainlessS]

Yeah, its just like bein' a bit pissed, but cheaper.

EDIT:
Some years back I had an inner ear infection (originally from chest infection, it spread),
balance systems went all to hell and if I closed my eyes for maybe 5 seconds
whilst standing up, I would fall flat on my face.
Woz well weird, only thing that sorted it out was about 6 or 8 pints of beer, then everything felt kinda normal. :)
(antihistamines and the like made no difference, only beer worked.)

[FranceBB]

Wow! That must have been annoying, but yeah I know what you mean. It's basically like when I go to sleep and sometimes I have the weird free fall thing due to my ears. The annoying thing for you though is that you had this while you were awake and standing up! O_O

[StainlessS]

When walking along the street, I had to take extra special attention to everything, felt like I was walking a tightrope,
and very conscious of my weaving from side to side, and of others thinking I was pissed.
(We take inner ear balance for granted, considerably harder when you have to use only your eyes.)

It's basically like when I go to sleep and sometimes I have the weird free fall thing due to my ears.
Dont know what thats like, I've never had the 'free fall' thing due to your ears.
[maybe they flap about or something, have you tried Blue Tack].

[FranceBB]

Really? You never had it?
Basically the thing responsible for your balance in your ears has some problems when you sleep and it might happen that it feeds wrong information to the brain. When that happens, you get the free fall feeling in which your brain basically tells you that you're falling even if you're actually just lying on your bed. It's pretty common, actually, I'm surprised you never experienced it before.

I've found an article about it by Steve Jacques, Head of anatomy, Leicester Medical School, UK:


The feeling is triggered by an involuntary muscle movement called a hypnic jerk that occurs when the body is in the transitional stage between wakefulness and light sleep, known as the hypnagogic state.

When the body enters a state of deep relaxation in preparation for sleep, this sensation can be misinterpreted by the brain as the body falling and therefore being in danger. So the hypnic jerk knocks you back into full consciousness. One proposed explanation for the link between “falling” and experiencing a hypnic jerk in the hypnagogic state is that it is a reflex that improved the chances of survival for our ancestors.


Although I wasn't totally happy with the explanation 'cause I found it to be a bit too technical, so I looked again on the web and I found this one which better explains it - for those who don't have any medical knowledge like me - by Matt Chamings, another professor but from Barnstaple, UK:


While awake, we are normally aware of the effect of gravity. For example, sitting writing this answer, I am conscious of the pressure of the chair on my bottom, as well as the fact that I can see that objects are orientated correctly along an up-down axis. Furthermore, my inner ear uses gravity to provide constant input about the position of my head.

While falling asleep, a crucial sensory relay station deep in the brain known as the thalamus becomes inhibited. The thalamus is the pathway through which sensations become conscious. If the brain doesn’t receive information on the direction gravity is acting, it may conclude that there must be no force pushing back against the body from the floor (or our bed). This is consistent with weightlessness or free fall.

[StainlessS]

Nope, dont recall ever having that.
However I once fell 60 feet out of a tree, hit about 3 or 4 branches on way down; sending me doing somersaults and cartwheels through the air
before landing with my arm splatting the branch that broke and caused my fall.
That arm/wrist ended up wrapped around the branch, broken in 5 places and dislocated in 3 places, my mother nearly collapsed when she saw it.
Anyways, no namby pamby hypnagogic state is gonna make a great deal of impact after that.

But, heres a bit more giggle juice thingy. [even worse piss'ed-ness inducing]

EDIT: That "hypnagogic state" thingy, is probably exactly what you see when a toddler is repeatedly falling asleep, and jolts back to being awake.

[FranceBB]

I looked at it the first time and it wasn't moving much, but I was on my mobile and it wasn't centered. I tilted the phone and made sure it was in the middle and yeah it looks like it's growing, but depending on how you look at it, it grows in one direction faster than in the others (or at least that's the impression I have).

Our brain sure works in complex and fascinating ways...

[VoodooFX]

OK, I lied, of course I've been on verge of falling asleep and woken up with a jolt. [never had that falling thingy though - not that I'm aware of]
I would describe that feeling as: suddenly a body starts to change position.

[Don't have hits on that Black Hole, maybe it's for the superstitious people :)]

[StainlessS]

This one is seriously messed up.

EDIT: If I concentrate, I can get it to stop moving, but relax and its off spinnin' again.

[Emulgator]

Use one eye only ?

[StainlessS]

Use 2 if you like on a bigger screen.

Are you sayin' that you cannot see it ?
(4 me, its hard to not see it)

(Currently on 10.0 inch screen, not so easy to see)

[StainlessS]

OOps, wrong thread.

[Emulgator]

I was too brief, I meant the wobbling disapeared as I watched it one-eyed only.
And today it wobbles even with one eye only, so seems to depend on my actual fitness.
Two-eyed doubles the wobbling ampltude. Nice one.

[StainlessS]

This not an optical illusion, but a practical tool. [no point in starting new thread just for this post]

There are cases when brain hears what it wants to hear. That's the reason misheard lyrics exist. This is like an extreme example

[ognirats]

I hate tiktok

same. by far one of the worst social medias out there.

[FranceBB]

same. by far one of the worst social medias out there.

You know, the other day I watched a person interview a young girl and he asked her some questions to understand the differences between generations. One of the questions was "which social media are you in?" and she started listing them (TicToc was in there). At that point the interviewer said: "Uh, I'm surprised you didn't mention Facebook" and the young girl said: "No, that's for old people, like my parents".

It was in that moment that I realized that not only I'm slowly approaching my 30s, but that some of my friends are indeed parents already...

For a person like me who often jokes about how young I am compared to the "old farts", I've never felt so old... :scared:

Below, with bins on (eye-glasses) could not see anything (no animal),
but take them off and can immediately see the creature.

EDIT: Actually, the image is a bit big for me on the D9 (difficult to see), is easier to see it via first link.
EDIT: I can see creature in above image with bins off, if I wiggle/scroll it up and down a bit.

[kempodragon]

I can confirm this. Glasses on, almost impossible to spot. No glasses, image was immediately visible. I'm nearsighted with astigmatism, can anyone farsighted try this?:D

[FranceBB]

No glasses, a bit shortsighted but I'll be long in my retirement before I'll ever contemplate the use of glasses. (Specsavers won't have me!).
Now, jokes aside, I can see the picture, but I'm a bit confused.
If I watch it from the front, it looks like a gorilla walking, however if I look at it from the side, it looks like a horse.

[StainlessS]

(Specsavers won't have me!)
Apparently, @ ~44YO (+- about a year or so), 98% of the population starts to require reading glasses [of those that did not already use glasses],
the docs dont really know why that 2% get away with not needing optical assistance for their entire lives.
(lenses stay supple)

Just one of the things that nobody tells you, but that you find out for yourself eventually.

[FranceBB]

Damn, that's a worrying statistic... :(
Looks like it's more than likely that I'll need them before retirement then... :(

[Boulder]

You might get by without glasses, but they make many things easier. I'm a little under fifty and I got my first glasses for everyday use (I use them if I need to see clearly far, like when driving) this year but struggled already for years :devil:

The irritating thing about glasses is that the brains adjust and then it's much harder to manage without them.. it would be interesting to test how long it would take to train them to go back to life without glasses :D

[StainlessS]

About 3 months, then back to square one, just like before you started wearing them [reading newpaper at arms length].
However, its just so damn convenient to reach for them instead of a having to struggle.
[Basically, your brain just gets used to switching off focusing when you use glasses, takes time to get it to start switching on again]

EDIT: This book, I got some years ago [when my eyes were going dodgy] from the local library.
Was first published in [I think] 1901 [EDIT: apparently 1920 for original version], and was in its 51st [or thereabouts] edition/printing when I got it.
Comes with an eye [similar to Snellen] chart, to assist in eye exercising so as to get by without bins,
it does work to some degree, but just too damn easy to use them [bins] "just this once".

EDIT: IIRC, W.H. Bates came from a family of opticians or optical scientists/hobbyists,
I think his father was one of those that investigated the case of the two little girls who took
photographs of fairies in their garden, and nobody could prove that they were fake
[including Arthur Conan Doyle and Harry Houdini] [EDIT: [B]Maybe I imagined this paragraph. :eek: {or maybe something about it in the book}].
https://i.postimg.cc/0jXC6mJs/images.jpg (https://postimages.org/)
EDIT:
Better Eyesight Without Glasses is not only the deffinitive source for the classic Bates Method, it is in itself a remarkablke phenomenon. In the more than forty years since this revised edition was first published, the book has gone through innumerable printings and is more popular and more pertinent than ever today. Dr. William Bate's revolutionary and entirely commonsensical theory of self-taught improved eyesight has helped hundreds of thousands of people to triumph over normal defects of vision without the mechanical aid of eyeglasses. If you think that your eyesight could be made better by natural methods, you are right.


EDIT: Wikipedia:- https://en.wikipedia.org/wiki/William_Bates_(physician))

William Horatio Bates (December 23, 1860 – July 10, 1931) was an American physician who practiced ophthalmology and developed what became known as the Bates method for better eyesight. The method was based in his theory that the eye does not focus by changing the power of the lens, but rather by elongating the eyeball through use of the extraocular oblique muscles; this model contradicted mainstream ophthalmology and optometry then and now.

EDIT: The unrevised/un-edited original version of the book is now in the Public Domain [see wikipedia] {Although on Amazon £75.00 in paperback}.
Because the copyrights have expired, the original version of Perfect Sight Without Glasses (or The Cure of Imperfect Sight by Treatment Without Glasses) is now in the public domain. In 1943, an abridged version was published under the title Better Eyesight Without Glasses, which removed some of the most controversial points, such as the claim that "perfectly remembering black"[4] is a suitable substitute for anaesthesia, and recommendations to look at the sun.[1]

From the intro,
On a tomb in the Church of Santa Maria Maggiore in Florence was found
an inscription which read: "Here lies Salvino degli Armati, Inventor of
Spectacles. May God pardon him his sins."
Nuova Enciclopedia Italiana, Sixth Edition.
Tis [IIRC] full of stories, eg Woman who had cataracts and had lens removed, could then see moons of Jupiter with naked eye.
EDIT: Nope, cant find that story, but there are several mentions of Jupiter in the book incl this one.
The extraordinary memory of
primitive people has been attributed to the fact that owing to the absence of any
convenient means of making written records they had to depend upon their
memories, which were strengthened accordingly; but in view of the known facts
about the relation of memory to eyesight it is more reasonable to suppose that
the retentive memory of primitive man was due to the same cause as his keen
vision, namely, a mind at rest.
The primitive memory as well as primitive keenness of vision, has been found
among civilized people; and if the necessary tests had been made it would
doubtless have been found that they always occur together, as they did in a case
which recently came under my observation. The subject was a child of ten with
such marvelous eyesight that she could see the moons of Jupiter with the naked
eye, a fact which was demonstrated by her drawing a diagram of these satellites
which exactly corresponded to the diagrams made by persons who had used a
telescope.
EDIT: The fairies stuff seems to be complete tosh, maybe I got mixed up with somebody else
when I was researching why my eyes were getting lousy. [memory is an odd/weird attribute]
