Dream of

I had a dream I was in this huge castle, with a courtyard and all the works. I was somebody important there, and I had guests. One girl, with dark, was after me. I ran up 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 that she had apparently taken from me, and strangled her with it. I killed her.
