This story is a sequel to One Day in the Life of Princess Celestia

Three days after an uncomfortable conversation with Princess Luna about a dream Rarity had about herself with Celestia, Twilight, and Luna, she finds that everyone is treating her strangely. What she doesn't realize is that everyone knows about the dream...but they think it really happened. What will it take for Rarity to get her life back to normal?

Ponyville has a problem: Twilight's friends all switched Cutie Marks, and the musical numbers are flying thick and fast.
Lyra has a problem: She can't handle the way musical numbers get into your head and take you over.
Bon Bon has a problem with that.

Reviews and other word-of-mouth:
"I just can't find words for how much I enjoy the ideas on display here. … I didn't expect to be rating something this highly, this quickly." –Bradel
"The Lotus Eaters was the story that made me realize horizon wasn't just good, he was really good. Then Fugue State showed me he was really good repeatedly." –Bad Horse
"a strange but intriguing story ... [horizon's] so good at this ponyfic lark that it's still a highly satisfying read. ★★★★" - Louder Yay
"This story is weird, and I mean that in a good way. … [Horizon] thought about how ponies might react if [musical numbers] were a constant in Equestrian life." –Chris

Fugue State now has a sequel!

In a world ravaged by the living dead, one man has outlasted those with far more strength, speed, and experience. His only advantages are his uncanny luck and peculiar inspiration. This inspiration has never led him astray and even promises a fresh start. All he has to do is build a strange device that follows no earthly science.

While Earth’s story might be over, this cog-jockey’s has just begun.

Princess Luna, carrying out her normal duties of watching over the dreams of her subjects, comes across one of a more intimate variety. Normally unfazed by such dreams, this one embarrasses her into leaving quickly. Despite her decision to never think about the dream again—like always—she can't help but remember a single detail from it. A detail so strange she feels the need to talk to the dreamer about it. Unfortunately, she doesn't know who the dreamer was.

Awkwardness ensues.

Celestia likes her routine. Tax reforms, grants, laws and construction projects are all a princess needs to be content.

It's just her luck that for Pinkie Pie, "content" is not nearly enough.
