After stopping the vid and looking at the comments the comments were moving. Is this common?
CRAP!!! Searching for other things on CZcams and landed on this video, and stared and the damn dots and they flashed and came back, and flashed... then I skimmed though the comments and realized that I was supposed to be searching for other things on CZcams in the first place, but now I forgot what that was suppose to be... Am I ADHDified?
Trying to read the comments after watchinh this video is like an LSD trip.
It is great
I dont know It's real or not.but for the very first time all the yellow balls disappeared for 5 seconds.then after trying couple of time it was 7 seconds.but now I cannot dissappear all of them for more than 3 seconds
Thank You Sir so much ❤❤❤
5 seconds done!!
adhd here, hardly one during half a second
I can do it if my eyes don't get irritated I have to close tjem
For 2 seconds I cannot see 3 balls
Who is come here after watching shorts
woo all the words are moving now
I got 2 dots away for half a second, I could barely keep it together
Is it a test only or it is for practice also?
The video did nothing, nothing at all. Sure add adhd, whatever I came to watch a trick vid and it didn’t work for me. L
I only want to focus on the things that matter in my life.
I could barely make them disappear
Gee, I wasn't even aware of the direction given that neither silhouette was wearing any undergarments 😂
I think im broken because the only thing that was happening was the screen just started shaking as the green flashy dot moved all over the screen
its hollow i dont under stand wdym guys????????
My vision has gone doubled and i see 6 yellow dots and 2 flashing ones the entire video 😂
I was confused at first why the dots kept shifting and coming back, then I kept doing it and held on for about 30s but after that I had to blink bc my eyes started to hurt
Mine none
I just noticed if you stare at the center and relax eventually your eyes will close and the entire computer vanishes!!
How to make
I swear it worked before
I don’t get it
hard to make it work in a small very reflective cellphone, but may work on nonreflective computer screen (y)
I can only make them disappear for 2 seconds
After staring at the illusion for 2 minutes straight I looked away and... I am blind.
What does it mean if you see 10,000 dots that are yellow?
BRAIN NEEDLE
Failed. And my world is spinning
but what does it MEAN about my brain
started anticlockwise, then clockwise. i just saw the og spinniing lady tho and she was only clockwise.
Made it to six seconds.
The screen started to roll
The are gone but for 3 -5 sek not more..
Five seconds is extraordinarily rare, according to the video.
source?
Yes. Watching full screen makes a difference.👍😎

marvelous
I can do anything I want
I can't even get 1
Eu amo essa música que você colocou nesse vídeo😊
Essa música é muito legal copiou com os planetas e as estrelas
His voice over is distracting 🙄🙄
I kept struggling to make all 3 disappear so I got bored and gave up
Watched this in school lol
ultrarare person. i very rare pers0n bcz 2 hour ago i stop see the dot. binod
1 in a 9 billion
As soon as all dots disappear i get dizzi because of the rotation of the grid
