The Unspeakably Familiar

[Universalchild]

Early twilight frost hardening
plangent to imperative; First time in a while that I've had to look up a word. I don't really like the sound of it, but it suits perfectly so I can't complain.
language learnt to clutch and curve
him clear of double jeopardy. I'm not sure what this means, but I admit this is likely my lack of knowledge.

Shadow boxers bob and weave,
hide and seek the scripted fall
softened by linoleum;
the sting of an averted cheek
stained a dark and bitter flame Why flame, out of curiosity?
discolouring chameleon.

Boiler bubbles, dripping tap,
carol singers, hiss of gas,
brown sideboard, aspidistra;
squeeze a bauble, tear a picture,
pilfer happy thoughts and crush
the unspeakably familiar. I like the way all of this sounds, it rolls off the tongue well. I understand the last two lines, but I admit I don't get the string of imagery. I thought maybe it was pieces of a picture trying to create a home/something like that.
