Box of Birds

A hypertrophy of birds, an amassing multitude of bodies, held forcibly and condensed down into a cube by unknown forces.  The compressed, sunken, hard, inescapable feeling of heartache, that fills and bears down, and pulls from the inside, suspended within your chest, big and hard and heavy.  The bodies of the birds swell out and the cosmic antimatter crush it back in, the heart has no room and each beat is strained and pained.  The birds are silent, their sounds muted by the nothingness which condemns them.
