I read a lot of books about dinosaurs growing up. One, thinking it was being helpful in showing young kids the scale of how large a dinosaur was, used a house next to a silhouette of a T Rex to show it's size. Unfortunately, that particular house looked just like my parent's house. And the T Rex's face was level with the window that would have been my bedroom.
So... I was scared whenever my back was to my window for a good couple years.
