chrysalism. n. the amniotic tranquility of being indoors during a thunderstorm, listening to waves of rain pattering against the roof like an argument upstairs, whose muffled words are unintelligible but whose crackling release of built-up tension you understand perfectly.
This is my favorite word and my favorite feeling. Whenever I listen to something like rain on the roof, or the swooshing of cars past my bedroom window, it's like my brain glazes over. No matter what the day was like or how I was feeling, all at once my mind empties, I go still, and let myself just quietly vibrate.
