What is vampirialism?

Vampirialism refers to the concept or practice associated with vampires, often characterized by the act of feeding on the life force or blood of others to sustain oneself. This idea is frequently explored in literature, folklore, and popular culture, symbolizing themes of immortality, power, and the consumption of others for survival. In a broader sense, vampirialism can also metaphorically describe exploitative relationships where one party drains resources or energy from another.
