"An ordinary zombie is slow, stupid and dangerous only for an unarmed and confused person in a confined space. Such zombies are called "sleepy." Having tasted any meat becomes smarter, faster and is a problem even for the gun-wielding living. Such nimble zombies are called "woke." But worst of all are those of the deaths that were able to get to the living, unconverted meat of an individual of their species. They change even outwardly, acquiring new opportunities, their intelligence increases, but all this: power, speed, cunning - is used only to kill the living.
