Murder in my mind

Have you ever had a dream that just goes on and on, and gets more and more disturbing? And then, at some point, something clicks in your mind after what feels like forever and you realize it is all a dream and you force yourself awake and it takes you a while to sort out what is real and what is not? That just happened to me for the first time. I won’t go into the dream except to say that it vaguely resembes aspects of A Simple Plan, and it was pretty weird.
