The first is when I met all you guys. Your family stuffed me with food because your little sister is manipulative and has pretty eyes.
The second was when I realized all you guys were my friends, and we beat Nightmare Moon together. The rest of them are all about magic. Rarity's special unicorn spell relates to finding gems, and I was able to mimic it. And then I turned a bunch of parasitic insect things into worse parasitic insect things.
Aaaaand apparently I'm a really, really powerful magician, and I was worried you guys would hate me for it.
My dreams have no sense of continuity, so my attempts to build a timeline for my other life aren't going well.
