Ghost Illusions in Clouds

Ghost Illusions in Clouds Screamer
A 30-second screamer that pretends to be an optical illusion video which shows a sad face hidden in a picture of clouds. It then shows a still picture of a cloud-filled sky. But at the end of the video, a grayscale and negative image of Regan pops up with the scream from What's Wrong? extra loud and repeated four times.
