During one night, Princess Luna was in her room, feeling uncomfortable while sleeping. And then, she ends having a very strange dream involving her and Twilight Sparkle.
The scene starts with Princess Luna in her room, sleeping comfortable, when all of a sudden, a voice called out for her name…
Twilight Sparkle: "Luna! Luna!"
Princess Luna: (Wakes up from her nap) "Wh-Who dares call out my name while I'm sleeping? Answer me this instant!"
Twilight Sparkle: "It's me, Twilight. I'm the one who called out your name!"
Princess Luna: (looks around the room, not seeing Twilight Sparkle anywhere around her room) "Twilight, where in tarnation are you?"
Twilight Sparkle: "Down here!"
Princess Luna: (flies down to the tiny-sized Twilight Sparkle, which has startled her) "Twilight Sparkle, how did you get this small? You're so tiny. I mean, you've never been this small. It's very unique for me to find ponies so small in my dreams."
Twilight Sparkle: "Umm, I don't know how I got so tiny, but look at you, you're bigger than I am. After all, being small is very fun, and I just like this."
Princess Luna: "Well, I better find someone to return you back to normal. You can't just stay tiny forever, you know…"
Twilight Sparkle: "I'm fine just the way I am."
Princess Luna: "What do you mean?"
Twilight Sparkle: "You see, it's not that bad for a pony to be tiny, like me. If I wasn't in your dream, then I would've been normal-sized by now. (giggling, and then gets really excited) This is like a dream come true!"
Princess Luna: "Thinking that this would be strange makes me feel both worried and confused, but I get what you're saying. I now understand why being at a different size matters. I guess you can just stay here with me for the rest of the night."
Twilight Sparkle: "Really? Yaaay!"
Princess Luna sleeps in her bed again, while the tiny-sized Twilight Sparkle sleeps on her blanket, and the two became quiet throughout the night.
Part 2:
The scene begins with Princess Luna and the tiny-sized Twilight Sparkle waking up from their nap, as it was morning.
Princess Luna: "So, you enjoyed your rest, little one?"
Twilight Sparkle: "Oh, of course… It really was such a nice rest to have for a long time. And now, I feel ready to return to normal again."
Princess Luna: "I knew you would decide to make up your mind."
The scene transitions to Princess Luna and Twilight Sparkle in the forest, with Twilight Sparkle ready to be regular once again.
Twilight Sparkle: "Alright, now I'm ready to return to normal!"
Princess Luna: "Here goes." (uses her magic on Twilight Sparkle to return her back to normal)
Twilight Sparkle: "(gasps) I'm back to normal… I'm back to normal! (gets excited again) Aww, thanks, Luna! You're the best!"
Princess Luna: "Well, everypony can change, especially by size. It may not be the easiest step, but you should learn this every now and then."
Princess Luna started waking up from her dream, and then got worried.
Princess Luna: "Huh?! What's going on? I had a strange dream… It's so weird, but it's over now.
The scene then ends Princess Luna going back to sleep, after having the most strangest dream of her life.
