Ex murders young girl

Date: 9/10/2017

I was with my ex at a random house, country setting. We were all hanging out and he killed the young girl that was there and buried the body near the driveway. He came to me told me he had and he had a reason. I was extremely anxious and was the only one who knew what happened to her. I remember seeing the spot that he had buried her. And older women who was the care giver of the girl started looking for her and thought she had run away. I left in my car as I couldn't handle the guilt. Horrible dream. Woke up so stressed and thankful it was a dream.
