I'm reading old journals of mine which is mostly healing. I was struck by this passage about why clutter is upsetting:
"I enjoyed the rest of the day in bliss just cleaning and vacuuming, actually. I decided that to people who suffer easily from sensory overload, introverts like myself, are troubled by randomness, because there is a potential Message in randomness. If you just have a regular pattern ABABABABABAB...there can be no message there. But if you mix it up AAABBBABAABBBAABABA there is much more information, potentially. Our subconscious is picking up randomness and trying to interpret it. You have to make everything more orderly to feel more comfortable, and not like the papers on the floor are talking to you."
And I'm still trying to clean, 20 years later. Some day I might reach my goal of quieting my surroundings.
