Looking back at the dialogue between the female psychic medium and Josh, it turns out that they are returning to this inner world of the black veil bride's painful childhood memories. That terrifying old house that imprisoned painful memories and tortured 15 dead people.
The female psychic used a chair to smash the mother of the black veil bride to death. The mother here is the black veil bride's own lustful memory, constantly tormenting her hateful memory. Smashing his mother to death in front of the bride in black veil as a child is equivalent to freeing the bride of black veil from the painful past. Without hatred, there would be no killing, and naturally there would be no desire to store the body.
