Dream About Murder In Church Graveyard

Started by being next to an old church, a man dressed as a police officer from mid-1800s was stood there keeping everyone back who also appeared to be from the mid-1800's. People were talking about a body being found in the grave yard around the church and whispers of murder. After a while a man and two children, looking around 5 and 10, led me away, and the children headed home as we separated and I went with the man. It jumped to the following morning and I was once again going to the church. Another child was there, young around 6 or 7. I approached and asked where the original 2 children were, as I had the feeling I was expecting them there. He took me by the hand and led me to the graveyard where I saw them both through mist and just started screaming 'No' over and over. Dream ended as I dropped to my knees.
