Amazing Mind Trick Illusion
The video prompts the viewer to stare at the dot and follow the directions at the end. Then an image of a forest is displayed as a background, to the point where the dot moves around the image. After a brief second, a computer-animated 3D head jumps in from above and screams at the viewer. Then the text "Got you!" is displayed with a link to the author's channel. There is a copy of the video titled "follow the red dot.mp4".
NOTE: The following video contains a screamer!
