Wow... there was certainly a lot going on in this episode. It opens with Nightmare Moon and Rainbow Power, and it just crazier from there. A nightmare monster created by Luna to punish herself escapes into the dreams of the Mane Six, and Luna takes it upon herself to hunt it down. This gives us the opportunity to find out what the ponies dream about, and the results are not disappointing. Naturally, the creature escapes again, this time into the dreams of all of Ponyville. (Goddammit, Pinkie.) This leads to quite possibly the weirdest battle I've ever seen on a cartoon, as Zap, Mistress Marevelous, Flutterbat, Princess Big Mac, Sir Spike and Giant Derpy battle a giant invincible smoke monster. It's just as strange as it sounds. I give this episode /10, as its weirdness transcends human numbers.
