Needing to clear physical space??

Over the past month or so but really speeding up over the week (or actually past few days especially) has been a sense of needing to purge and de-clutter my physical surroundings. I have been a whirlwind of cleaning, tossing and NEEDING to clear. I simply cannot bear the clutter any longer and it is really a deep feeling. Does anyone have a thought on what prompts this? I have always needed a peaceful and fairly orderly surrounding and go through de-clutter stages but now I REALLY do more than ever before (and this recent stage of purging has certainly clashed with my family of pack rats :)) (If it were just me, I would recycle/give away half of our stuff.)
