Last night I deampt I was Twilight Sparkle;

Rarity had apparently been experimenting with dream magic, and noticed there was someone attacking people through overly vivid dreams to make them exhausted and worn out, and asked 'me' to see what I could do about it. I, in the real world, kept waking up because what "I" saw in the dreamtime really was overstimulating, but I kept falling back asleep into the dream, trying to work out all these kinds of puzzles and scenarios to break up the dreams.

"I," Twilight, realized that it wasn't Rarity, but whoever was attacking that sent the message, and was able to start shunting out the dreams and finally stop them, as it seemed Fluttershy was nearly having anxiety attacks from it all, and Rarity was only the first victim.

Confound these ponies, they drive me to write fanfics... fandreams? It was lucid dreaming after I got it under control, but still.
