From Gary Barwin:
A form of darkness that isn’t visible.
Here’s how. Imagine it’s not your eyelids, but the rest of you which opens. Where? Close. You’re always close. If there are colours beyond the visible spectrum, ultraviolet, infrared, there are other forms of dark. Colour is fast sound just as sound is slow colour. Silence creeps like sunlight on your skin, and you aged eight, lying in the garden, and your mother calls from the side door, come inside soon it’ll all be gone.
