Question about a dream?

Maybe something happened to someone you know, or just something you heard about. Could even be a result of the tragic news stories we see everyday, or a scary movie, etc. Also, maybe there is something that happened to you or something you witnessed that is now coming out through dreams. Just remember, dreams are not real, and if you have another dream like that, you can say (in your dream) "Who are you? What do you want? This is a dream and I can wake up whenever I want!" You'd be surprised how well that works to wake yourself up.
