What does it mean when you dream of a kid with your friend and he dies to protect you and the kid?

All of the characters in this dream represent different parts of yourself. The kid is that part of you that is innocent and vulnerable, curious and creative and trusting. The friend represents that part of you that recognizes the value of true strength and sacrifice. The underlying message of this dream might be that you need to decide which aspects of your life should "survive" and which should be "sacrificed" so that other parts of your life can fully develop.
