Ok, first thoughts over coffee:

The open vowels throughout are work really well with the content. A sort of numbing spin.

Consider:

Un-spun from the hum of
blurred rhythms sound bytes stun guns
trigger targeted memories in rigor

Love that line break on "rigor," because my mind immediately jumps to "rigor mortis."

Moments hook, hang threaded
Gallows swing noose necked,
sing hymns of torn sheets

Put it in the present tense and took out the gerund. Did you mean "the hook that belongs to the moment" or "moments hook, hang threaded"? I wasn't sure. My suggestion is obviously for the latter.

Un-do the done
do ties undue
blank paper lies white

Taking the "ing" off "do" stresses that "oo" sound a little more. Is it lies, lay, lays? Guh. I can never remember. I think it's lies, and I like the double meaning.

Note in Trust
bellow from breast
snap smartly in protest

Again, just a shift to present to make it more immediate. This is a fun one to read out loud. Thanks for posting it. Hope this helps.
