In Polish and related Slavic traditions, the strzyga (or strzygoń in masculine form) names a predatory revenant shaped by beliefs about abnormal birth and a divided soul. Ethnographic collections and later literary retellings describe persons born with two hearts, two souls, or a second row of teeth as destined to become dangerous after death.

Folklore often holds that such a person dies young; one soul passes to the afterlife while another remains and reanimates the body. The returned strzyga was said to hunt at night, sometimes in owl-like flight, draining blood or vitality from sleepers, livestock, or travellers — though some tellings cast the figure chiefly as a death omen rather than an attacker.

Scholarly work on Slavic revenant beliefs, including Polish sourcebooks on the living dead, links the strzyga with broader fears of improper burial, epidemic death, and bodies that would not stay in the grave. Archaeological discussions of deviant burials in medieval Poland — prone interments, heavy stones, decapitation — are often read alongside these narratives as practical responses to anxiety about the restless dead.

Modern fantasy and vampire fiction frequently borrows the name, yet regional accounts should not be collapsed into one canonical rule. The strzyga belongs to a wider Slavic family of returning-dead beliefs that includes the upiór and related figures, each with its own local vocabulary, burial custom, and remedy.
