my dead dear friend

I had this dream. An old friend of mine and i were in the school. It was just us. Like we were the only two people in school. We decided to ditch our class and walk around. Then out of the blue a friend of his came out and stabbed him directly in the heart.. he died instantly. I didnt even get to say goodbye. I woke up crying and calling out his name. It felt so unbelievably real. I had to check his facebook to make sure he was alive. I think about that dream. It kills me. its what happened in real life. he is gone now and i didnt even get to say goodbye. who knows what kind of person he is? i have heard things. he has changed, gone. My friend. He is here, but he has a different look on his face, a different intake on life, worries about the wrong things. This has been the 5th night i have had this dream over and over watching him die. Just taken away from me.
