Strongly Recommended Stories:
The Brightest and the Best by Pineta - The events in this story are considered to be completely canon to this timeline and explain Twilight's entrance exam to Celestia's School for Gifted Unicorns. I cannot recommend this story enough.
MLP Annual 2013 - "The Fall of Sunset Shimmer" - As above, the 8-page short comic in the beginning of the Annual is also considered to be canon, though with some major variations.

Version 3.0 Edit: Extensive grammatical and mechanics changes. Adjustment to timeline of Sunset's second mirror experience.

Fluttershy has a problem: she keeps waking up with strange dreams. What has been going on? And what is that delicious metallic taste upon her tongue?

Warning: Contains Flutterbat and Silliness. Consult a Doctor if pain persists.

Supporting Cast: Rarity, Twilight, Rainbow Dash, Pinkie Pie, Celestia and Luna.

When Rainbow Dash tries to do thoughtful things for other ponies, it generally turns out pear-shaped. Which, of course, is what happens when a pony as unthoughtful as her tries to do such things.

But, hey, what's a bit of a mess when it comes to making food for one's friend? It shouldn't be that much of a bother, right?

Right?

My heartfelt thanks to Door Belle and Garnot, without whom the story would not have been legible (much less enjoyable).

Now with a review on Seattle's Angels! Check it out!

Through countless centuries, Princess Celestia has remained a steadfast beacon of benevolence, kindness, wisdom and grace. Everypony knows the Princess of the Sun cannot have a dark side.

Sunset Shimmer is about to find out just how wrong they are, and in doing so, find that Celestia understands Sunset more than she ever thought possible.

Historian’s Note: Dreaming in Dawn's Light occurs several months after the events of A Royal Problem.

Twilight Sparkle may have shown Starlight Glimmer the error of her ways, but Starlight is still new to the concept of true friendship.

Fortunately, Twilight has true friends in high places. Rarity, for example, is always glad to lend a hoof when it comes to bringing out one's personal elegance.

Morning Breeze. A mare in the esteemed royal guard. Certainly not a rarity, but still it's an accomplishment nonetheless. She has served the night guard to the best of her ability, and though never personally standing guard around her princess, she takes great pride in her duty. So when she learns that she is to be reassigned to make way for the return of the Lunar guard, naturally, she is a bit upset. Especially considering the Lunar guard is made up of thestrals, bat ponies of ancient times that disappeared after the fall of Nightmare Moon. Her irritation at being replaced by, thestrals, of all creatures, has her frustrated. But a chance encounter in the halls of Canterlot castle may reveal more than what she perceives.

Rainbow Dash walks into Carousel Boutique and asks Rarity out to breakfast.

Only...Rainbow Dash is acting somewhat...odd.

Concerned for her friend, Rarity spends the day with Rainbow Dash. But the bizarre new habit Rainbow Dash has developed quickly wears on Rarity's nerves...

In a darkened forest, a cult attempted to bring the spirit of King Sombra back to life. Their goal; imbue the spirit of King Sombra with far more dark magic than he ever had, and take over Equestria. When Twilight Sparkle intervenes, things go wrong, and something else is summoned. Something that Twilight is familiar with, and hoped to never have to deal with again.

Something that may not be worse than King Sombra taking over Equestria.

Something far, far more obnoxious.

One evening on the eve of the Grand Galloping Gala, Starlight Glimmer can think of only one pony she wants to be her plus one, her best friend Trixie. Seeing no other alternative but to face her fears and ask Trixie out herself, Starlight pays the show mare a visit. The discussion that ensues however, is far from what Starlight was expecting. She just can't understand how Trixie is only a size Ursa Minor.
