You know its buildings and weather that bring back feeling memorys for me too. I think it was because as a child, stuck with my fears and not having the words like you say, buildings and weather became my compass, I related to them in their starkness and and alonesss. A tall warehouse building reminds me of my saddness at being alone with my fears and rainy days I used to walk with me. It was like mr moon was crying with me.
