Twilight has had nightmares in the past. It's not something she isn't familiar with, and she's even done quite a bit of research on the topic. And she knows better than almost anypony else what a nightmare can and can't be, and how it can or can't hurt her. Still, sometimes, some dreams do feel different. The cold feels just a little more real on her skin than usual, the images a little more vivid. But it's just a dream, right?
