I need help on a dream, PLEASE!!!!!!!!!!!!!

I dreamed I took my children to a drive in movie, then we were going home, but we had to stop at a gas station first. I went inside to get something for my kids, snack foods, and left them in the car with person x.I don't know who this person was, but for some reason I was ok with leaving my kids with them. I came outside put the snack foods in the car and then told them I would be right back that I had forgotten something. I went back in, came back out with something important in my hands that meant something very important and gave it to the other person in the front seat. Then I told them I had to go back inside. I was going to buy some cokes. Then I heard this terrible noise. It was a screaming, and I looked outside. The person in the passengers side of the car kept running over this dog. They were bashing it's head in by driving over it and its eye came out of the socket and then the eye was completly gone and laying there on the ground. Then my kids were sitting there in complete shock. This other person looked at me, with the most satanic look I have ever seen on someone else's face. They growled at me with much venonmous hatred in their voice and told me it was all my fault. They picked up the dead dogs body and carried it toward the trash can, then the dog came alive in their arms. Yet, instead of the dog attacking them it came after my daughter. I don't know with certainty that it killed her but there was blood everywhere, the eye socket was staring at me, and the dog looked at me with pure hatred and my daughters voice was screaming. I could not get to my daughter, I could not move it was like I was stuck. I woke up screaming my boyfriends name, and went to the bathroom, everywhere I looked this dead dog was haunting me. Of course it is gone right now but it is not as trippy as it was. But it still bothers me.
Please help.
