In which I remain a mystery

There’s a kneading in my chest, a drawing out, a punching in, a folding over. I’m not quite sure what the end result is meant to be (and I’m doubtful it’s worth all the commotion). My lungs are doing their best to press on despite the surrounding churn, thin breath in, thin breath out, a constant battle against diaphragm.
Shoulders are corded tight, ratcheted two clicks past comfortable and tugging up toward my beleaguered neck. They too, appear to know something I don’t.
It slithered in from somewhere, maybe alongside that dream last night with all that frantic dismemberment and panicked swipes of fingerprints. Maybe it came in as I drew away from the present and slid toward the past without shuffling my thoughts into order first.
It’s refusing to answer questions in any case.
This feeling is the one that wants to consume everything in sight. Fill all bodily cavities until there is no room for churn or movement or tightness. There is only the sturdy counter press of repletion.
It always passes, sliding out of my skin and into another’s without any pattern or cause. In the meantime, this mound of flesh I call ‘mine’ will continue to jitter and jolt its way onward, desires and motives entirely opaque.
