What colours... What light...

Let the light not be
It keeps me from lightening
It’s all heavy in there
Dense, intense; heaving doesn’t work
Sucked from within, contracting, I gasp for some air

Let the light not be
Let me shed this cloak
It’s heavy and wet
Bones crushed, being choked
Various colours of various lights
May be charming, I want nights
They help me alight
The burden of light
Which I carry, on my frame
Which is my person, which is my name
Easily off in the dark
But in light, without a mark
How it goes in
To be my flesh, my skin
Broadens the frame, does away stoop
I stand tall, and I droop
