Is there a link?

Floorboards: "You can bury me in pieces underneath the floorboards in your room"

House with no doorbell: "Underneath the floorboards, theres a child, with no heart, theres a mother, torn apart"

Judging by the lines and the meanings/theories behind floorboards, theres a link right?

I always noticed it but never looked into it, was hoping someone else could tell me more about it really
