Dream

I had a dream about a lady who would take children and take their limbs off and put them in paintings.She had people and a dogs who would help take the children, and she'd come through little tunnels in people's houses that she'd create. I was supposed to help her take the children and I wouldn't but then she took me and my family and tied us up and was going to cut us up and put us into the paintings but I woke up before that happened. What does this mean??
