Ghost Illusions in Clouds

Ghost Illusions In Clouds Screamer (Scary!) is 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. After some seconds the text "You just got pranked by a screamer..." is displayed.

Description
Not for people with heart conditions...

You must spot a sad face in the clouds. The face color is black. If you found it, I will subscribe you :P
