I seem to have been awaken in a crowded, black room. Although, I can't see anypony at all. The atmosphere just seems crowded, and I don't really like it one bit. The atmosphere also screams nightmare, but, I can't bring myself to wake up, no matter how hard I try.
I find dream-me walking towards the exit of the library, and I can't stop myself. It's like somethings luring me there. I walk outside, and it looks like a gem-bomb hit ponyville. I am instantly inspired to create all sorts of outfits, it feels like my brain can't take it anymore. I lift one gem, look at my reflection, and immediately drop it.
My face has been mis-shappen, into a ugly twist of wrinkles and rags. I scarcely look beautiful anymore. Out of nowhere, I'm in the middle of Canterlot. Many ponies ridicule me, making me cry, which is probably sad, hideous, and a bunch of other things mixed into one. Princess Celestia comes, sees me, and banishes me into the Everfree, where I am claimed a witch by sweet little Apple Bloom.
I wake up, gasping, then check the mirror to see if this was true. My witch face stares back at me.
I wake up again and find out that I'm still beautiful.
Twi's Notes
It seems as if Rarity is scared to turn ugly. She thinks that, if she gets wrinkles, no one will like her anymore. I'm not quite sure about the 'gem bomb' part, but, maybe it has to do with her talent? Rarity should not consider aging (thus the wrinkles) as a horrid state, simply a part of growing up.
Overall, She shouldn't worry about how others think. Even if she is transformed into, as she said, 'a witch in the Everfree', we would all try to get her to open up to the world again and try to help her. She shouldn't worry about this type of stuff.
Then again, Rarity is Rarity...
