Nightmare Night goes a little differently and leads into a spiraling staircase of events. the Night will forever be mixed with the scent of Lavender.
this is basically my old story Lavender Night, but revised and redone completely, only the basic story elements are there

A pony from Twilight's past returns. Nopony should ever be forgotten.

There comes a time when the light must go out; but how do you know if you've burned brightly enough?

Apple Bloom had always dreamed of the day. She just never dreamed that it would be a nightmare.

Luna is on her way to visit Celestia, but hears her squealing for someone to 'stop!'

She walks in on Twilight on top of a red-faced Celestia, and the two of them react like guilty teenagers. Just what the buck is going on here?!

Princess Celestia tires of constantly being surrounded by decorum, deference, and formality, and decides to take a day off from being Princess. But visiting Ponyville incognito is harder than she expects. Will she be able to fit in and make friends without blowing her cover?

"Dear Celestia, what have i got myself into?" Twilight and Rainbow Dash have always had each others back, but now Dash has no choice but to put her life in Twilight's hooves. Due to one of Twilight's magical experiments gone wrong, Rainbow Dash has been changed back into a 3 year-old filly. Now Twilight has to find a way to to change her friend back before the effects become irreversible. But will Twilight's attitude go from 'mother' to 'lover'?

As her ears slowly adjust to the sounds around her, the humming of several monitors surround her body. It is impossible to hear anything, her friends, the doctor's voice, through her blurry eyes, she notices an absence of a certain orange earth-pony. With her entire life ripped from her back, Rainbow Dash must learn how to handle her now earth-pony life, all while Applejack is simply trying to be able to look her dear friend in the eyes without the overpowering guilt bringing her to her knees.

With gloom on the rise and guilt consuming, is there any way these friends can repair themselves without hurting one another?

AppleDash.

With the time she has left, Rainbow Dash seeks what is truly important in life before moving on.

Rainbow Dash is torn between fulfilling her dreams and acting on her feelings for Twilight Sparkle. Does Twilight not feel the same way, or is she simply oblivious to Rainbow's intentions?
