Duke Zhou dreamed that dogs ate dogs.

I dreamed that two dogs at home seemed to have lost one, and suddenly the dog came back by himself. I was still talking to my boyfriend at that time. I don't know what to say. Suddenly he said, look, it killed him. I turned around and saw that the poor puppy was brutally eaten by the big dog. I saw how cruel the grave was, and I watched it drag the puppy's intestines out. It is still there, and I am anxious to stop it. My partner is still talking to me, but I don't remember anything. I can only watch it until I die. It's terrible. I don't know what this dream means. Please help me explain.
