I was celebrating with my twin sister and our friends when something in me snaps. I kill my sister and her friends with my own friends' assistance. We remove all the evidence of us being there, then escape the building before we are caught via a flying ship that looked as if it were made for a pirate. I was plotting against another that I held close to my heart. I don't have a twin or a sister. And I don't know who I was plotting to target next.
It might be from books/ movies you have read /watched , most dreams are bits and pices of stuff from life and dont mean much .
