It's all about Awareness.

This dream was pretty short and pretty badass. Here I am looking out side my bedroom window, Suddenly this girl was looking at me, She looked quite familiar but I really didn't know who she was, So suddenly I turned away and walked back away from the curtains. She comes through the window and breaks the glass wielding a Katana sword. She tries to chase me and attack me with this blade and I woke up.
