Echoform

I held the breath
It shimmered in the depth
You didn't speak
Cause tension hit its peak
The echo moved
No trace approved
It bent the air, then broke the line
No breath returned, no shape was mine
No signal came
It flickered through the frame
I traced the fold
It shattered in the cold
The breath diverged
The shimmer surged
It held the fold, then tore the seam
No signal rose, no pulse, no beam
The echo stayed
The shape obeyed
It cracked the mist, then split the sound
No shimmer held, no pulse was found
