With the number of nightmares in Equestria slowly growing, Princess Luna finds that she has her hooves full more often than usual. So, in order to lighten her workload a bit, Luna chooses an apprentice to learn the arts of dream walking to assist her.
Tasked with chasing away what are literally some of the worst fears she has ever faced, Fluttershy finds that sometimes, nightmares can be truly terrible things...
And sometimes, ponies never really escape them.
