You blink, and you feel a churning in your core. You reach and grasp at your chest, gasping for air. It is too late.
A large incision develops on your torso, starting from your heart to your navel. A deranged surgeon from beyond our plane.
Your body makes a heaving motion. Out from your cavity emerges a sphere of light. The body ages thirty years in five seconds.
Without a body the soul is fragile and cold, like an untended egg. No longer bound to our arbitrary physical laws, the soul seems to simply disappear.
Your old vessel is now a dry husk, crumbling and useless. Everything in your previous life is now void.
They have adopted your consciousness.
