In the A. D. 1300 in Poland, more precisely in the region of Kashubia, was coined the term "nachzeher" to define the female vampire, or "chewing the shroud" or "devourer of the night."
The Nachzehrer would be a special kind of vampire who lives in a constant state of numbness in his grave, without understanding what is happening around and just like a child chewing spasmodically in her dress.
The theologian Philip Rohr's, in his presentation at the University of Leipzig, "Historico-Dissertatio Philosophica de Masticatione Mortuorum" also known as "chewing Mortuorum" (1679), describes in detail the behavior of these dead.
The theologian describes and justifies the phenomenon of vampirism as demonic possession and considers unjustified any violent action against them. An action against a corpse is inevitably against God and therefore must be condemned.
