Vietnamese ghost lore is not a distant relic of the past—it breathes within the rhythm of daily life, shaping traditions, rituals, and unspoken rules that have persisted for centuries. Unlike the structured underworlds of China, ruled by Yama Kings, or Japan's ghostly vengeance narratives, Vietnam's spectral realm is a shifting landscape, where spirits interact with the living in unpredictable ways. The unseen is woven into the fabric of existence, not merely as superstition, but as an accepted part of reality. Beneath the well-known legends lie hidden corners of Vietnamese spiritual beliefs—rituals, sacred sites, and ghostly omens—that continue to shape how people navigate their world.
