The talkers

The talkers are like human,but they're dead.when they eat a human brain or eating lithium they become normal,acting like humans,but when they get hungry,they turn into a cannibalis human with rage,they wouldn't stop after eating brains or lithium.when they want to eat, kill them or just give them lithium cookies(watch znation seasons 5 to know about them,TV or netflix) that all I know about them. Citizen z, over.
