Dream of mother

Well my dream was about some guys breaking into my house and shot me in the arm, my sister, brother and mother was home. my brother was down stairs with me and i told him to go upstairs and call the police. while i was downstairs with all the men who shot me in my arm. i start to talk to them and tell them why they should not do this, after that they put down there guns and they helped me by wrapping a shirt around my arm so i will fill less painful. they shot me and then they helped me, its something about that, that i wonder why they did that instead of just shooting me to make me die
