We lost our house and most of our belongings in the flooding caused by the remnants of Hurricane Gloria in the mid-80's. Escaped by kayak with 5 feet of water in the house. For several years after that, this feeling of mild but pervasive dread would settle over me any time rainy weather set in for a few hours or a few days. Took me awhile to recognize what it was about. That dread doesn't come over me anymore, but I won't ever live on a 500 year flood plain again.
