That not-quite-with-it, not-quite-keeping-up, not-quite-actually-in-control feeling. The not-enough-sleep, a-bit-hungover, just-been-Tango'd feeling, like you want to shake the muzziness out of your head. And your life. When you stop in the middle of a sentence, staring at the inside of your forehead with your mind's eye, lost in a trance, and someone interrupts you and you say "Wha...? Umm..." That feeling.
