I wonder what it feels like if worms were to come out of your body and you are still alive to see it.

Parasitic Wasp larvae and caterpillar host.
As the caterpillar feeds, it little realises it is eating not just for one but for many and not its own. Swimming inside the caterpillar’s ever more bloated body, parasites live on the blood of their host. They are growing too. These uninvited guests – larvae impregnated by a parasitic wasp – will soon become masters of their unwillingly accommodating slave. Before long, their teeth will be sharp enough for them to slice their way out of the caterpillar – eating it alive from the inside out – while their host becomes a zombified bodyguard, protecting and ultimately dying for its murderous, newly hatched brood.
