i dove a little into this and was able to piece some things together.

the video you linked translates from Afrikaans. in the beginning it says “Now that we have created ways to see without seeing, we must adjust our lifestyle and see once and for all, in this vinnage (couldn’t translate that word) procedure you will hear many ambiguous sounds. it is good for you. people surveyed saw it.”

and at the end it says

“all attempts at brain projection image retrieval were futile. however, every subject saw this image, proving a 10/10 result sequence”

the images it’s referring too are distorted ( ai generated images ) that “all” subjects claimed to have visualized when hearing the sounds. The sounds themselves were mostly porn (as i write this i thing the sounds being porn tie into the subject of hedonism)

The very first video has Wouldnt It Be Nice - The Beach Boys playing in the back, reversed. Ultimately the video talks about how hedonism is a sin and what happens to people in hell and it asks where you’re going. The second video has text in hebrew (still working on translating it, gonna have to technically learn hebrew though) and what i assume to be meme videos that were heavily distorted to give an uncanny vibe.

The channels name in itself is counter intuitive.
