Strong video hypnosis is the most horrible screamer

Hypnosis is a Russian screamer video created and posted onto YouTube by a user ANTImgn on June 20, 2015. the video itself disguises as a normal spiral video, where it tricks the viewer from concentrating on the screen by adding an unexpected screamer at the end of the video.

The video encourages the viewer to focus through the loops, spirals in black and white, while the music of a silent piano plays very softly. That's the majority of the video. After a while, however, the SCP-450 screamer interrupts before returning. More than 300,000 views were collected in the same spiral.
