I'm no expert, but IMHO one possible way of looking at it is:
The house represents the body. The furniture inside represents what you've learned, your morals, your emotional makeup/bagage & how you see the world- your world-view, how you judge others... Your dead mom taught you and raised you & instilled things in you, ideas that you may have outgrown, ideas who's time has passed (cobwebs), emotions that you can mature beyond, heal, grow, gain awareness... cleanse, with the aid of perhaps divine guidance ultimately guiding you to see truth as it is and grow, and perfect more. Perhaps it is now a time of growth, or it is coming up, and intense growth can mean the dreaded suffering... well, beloved to those who know, cause it's worth it in the end, and try to see the end of it all. Have faith.
