Buried knife behind the house

Date: 2/10/2019

I took a nap this afternoon, in my dream my mom and my mother in law are entering room crying, they say father of my godmother (she is also my best friend) called. I sense some tragedy happened and I start screaming" what happened, what happened". My mom is just looking at me and she won't tell me. She was just staring at me. In my dream I keep asking yelling for around 5 minutes, no answer. Then my husband approaches me taking place of my mother, I scream again " what happened, is my godson OK???" (in real life he was sick) and my husband with rage about what happened just tells me "I am keeping the knife buried around your house". That's when I woke up. What's the meaning of this dream? What buried knife means?
