In a weird way, the dark exposes our true selves. Out come the fears and hesitations, the worries, the memories and the dreams. We put our masks on the shelves again, to wait for morning and sunlight and prying eyes.
It seems like your lying with someone. It's mostly focused on the subject, but then there's the:
"Or who you claim to be"
maybe someone else is shining too. Maybe there's fear of shining in front of someone, unless the comfort of pitch black is there.
Anywho, I like this. It's nice language, brief but not fleeting, and there is a feeling of shining through the loneliness. When all is cold and dark around us, our heart still beats warm.
Either that or you're naturally luminescent like the deep sea angler.
There is such a feeling of isolation in this peice and I can't really tell if this isolation of by design to avoid any possible hurts that life can deal out. Bring that light to the daytime and you'll shine doubly.
