For years I've dreams in which the world is suddenly menaced by a Tyrannosaurus Rex Apocalypse. Well, zombies are so predictable...
What better antidote to night terrors can there be than a jolly song about dinosaurs?
And if you want more, and crazier, there is of course the Motherfucking Pterodactyl song.
(Yes, I know pterosaurs aren't dinosaurs, strictly speaking. Feh. Nerds.)
