Stare at the dot for 15 seconds

Stare at the dot for 15 seconds is a screamer video uploaded to YouTube on April 8, 2011 by Kieron Davies.

The video shows a blurry cyan dot inside a larger green circle (with the viewer obviously being instructed to focus on it). A second into the video, Thinking of Me by Olly Murs starts playing. Nothing else happens until the very last second; fittingly after 15 seconds, when the music abruptly stops and the What's Wrong? face appears; alongside a short, hoarse-sounding male scream.
