Summary
The story starts with Spike having a nightmare, in which he is outside at night on the streets of Ponyville. He hears Twilight ask him what he is doing out at night, and her replies that he didn't even remember coming outside. Twilight says that he was just sleepwalking and that they should go, but her lantern flickers and laughing comes out of the darkness behind her. Twilight is whisked away in a flying chariot. Spike runs after her, and discovers that they're taking her to Nightmare Moon's castle. He suddenly finds Nyx, stepping out a of a dark alleyway, not wearing her disguise. She asks what he is doing, and he explains that he has to save Twilight. At that moment, the castle changes into a stage and Twilight is standing under a hangmare's noose. Spike screams, "No!" and continues to try and save Twilight, but Nyx blocks his path, asking him if he wanted to play with a maniac grin. He tells her to get out of his way but Nyx replies by saying, "Is that any way to speak to your queen?!". She grows taller than all the buildings and attempts to squash Spike, who runs away, still attempting to save Twilight. Spike trips, and Nyx catches up to him, squishing him with her hoof. He watches as somepony bucks Twilight off the stage with the hangmare's noose around her neck. As she falls, Spike screams, "Nooooooo!"

Spike wakes up in the library, panting heavily after his nightmare. Nyx asks him if he was okay, and he tells her he just had a bad dream.
