Curious since this is also your birth chart, and shows the home that you build for yourself as an individual. Have you taken more of a plutonian approach to your own home based on your other chart configurations? Cleaning binges, throwing everything out?
I do know someone with neptune in the 4th, who is a hoarder and obsessively collects very specific things. Was not raised in a hoarding household though, but the grandparents were hoarders.
Interesting question.
I don't always realize things are piling up because I store items in places I don't access (go ahead with the psychoanalysis on that one). Once I "re-discover" such an area, a purge begins. It may or may not stop with that particular area.
Other times I feel the need to discard possessions if I fear that I've somehow become attached to them or if the items represent a part of me from the past.
It's funny that you asked this, because I was asking myself the other day, "what can I get rid of?" I keep a barren living space, so I can't find anything to discard at the moment.
Strangely, I once allowed Trader Joe's grocery bags to pile up in a corner of my apartment, because I thought I might "need" them (I kept even more bags - that I did use - inside of them). I felt suffocated by all that junk but wouldn't remove it, just like a hoarder, I suppose. I couldn't take it anymore and got rid of it all. I've never done anything like that before or since, and I have my theories.
