What is the difference between the Drud and the Alp?
Both describe the same basic occurrence, the nocturnal pressing down on sleepers, but the Drud is more strongly rooted regionally in Bavaria and Austria, where she is often merged with witch belief. The Alp is regarded as the more widespread, supra-regional name for the same night-hag concept.
Why is the Drudenfuß regarded as a protective sign?
According to folk belief, as soon as the Drud catches sight of a pentagram, she is compelled to count its lines and can find no end, which prevents her from entering. The sign was therefore placed on doors, stables and cradles.
Can one become a Drud oneself?
According to the belief of the Oberpfalz, no one became a Drud through their own fault, but rather through an error at baptism or through someone else’s malice. Tradition therefore also knew ways of releasing a person from this curse again.
