Trick Your Eyes!

(SCARY PRANK) Trick Your Eyes! Optical Illusion is a screamer video. It shows a moving hypnosis spiral. After 55 seconds has passed a picture of Regan MacNeil appears along with a scream. The picture seems like it's moving because of the effect the spiral has to your eye which makes it more startling.
