Dream of

I was in a castle. I was a princess. A dark-haired girl was chasing me. I climbed the stairs of a tower that opened to the sky with the intent to fly away. When I got to the ledge, I realized that I couldn't fly, and I almost fell. I ran back down the stairs and confronted the girl. I took an heirloom necklace with a purple flower on it that she stole from me, and I strangled her with it. I killed her.
