Sometimes I wake up in the middle of the night and the house is oddly quiet. In those rare moments, a calm settles over me. My mind rests and I'm relaxed, at peace. At least for a few minutes. Then, my mind disquiets and goes back to yammering at me like an overcaffeinated child. I've experienced this sensation a few times since I was a kid. Today, it happened at 3am. Ah!It's a strange sensation.
