An imitation of cheap animation. A group of others and I are walking along to the left. We’re centered in the frame. Behind us, moving slowly from left to right is the silhouette of passing hills. Then the frightening part happens. The silhouette of a Tyrannosaurus Rex is moving between us and the hills. And the entire scene keeps replaying over and over like a film loop. We walk, the hills move slowly, the T-Rex creeps up, we run ahead; we walk, the hills move slowly, the T-Rex creeps up, over and over and over.
This may have been influenced by Scooby-Doo animation.
