Ok no need to freak out, no need to freak out...
Ok I'm soooo freaking out! People don't have hooves and I'm pretty sure people don't grow tails!
Alright, let's calm down and think about this logically.

There was probably some dopey new drug in that sparkling, cupcake and I'm hallucinating this whoooole thing.

So if I wait just a little longer everything will be juuuust fine.
Ok. Alright, that's plausible.

"What's plausible?" comes the questioning voice of Twilight Sparkle.
Gaaah! Who said that?

"Ummm, I did..?" Twilight says.
How did you read my mind!

"Ummm, you were kind of talking out loud the whole time. Not very hard to miss" Twilight admits.
Well, alright then.

"As I previously asked, what's plausible?" Twilight asked curiously.
Oh, that? Well it's plausible that I ate a drugged cupcake that is making me think that I was turned into a pony or I have gone completely insane.

"Oh, is that right?..." Twilight mutters.
Yup.

Twilight Sparkle backs up slowly. "Oh, I'm sorry I just remembered that I have a book to finish so I'llbegoingnowbye! Twilight runs off.

As I stare blankly after the strange PURPLE pony I came to a realization.
I've gone insane.
