Welcome back to Our Weird World! As we continue celebrating the theatrical rerelease of the Harry Potter films, this week we’re exploring the legend of The Grim—the spectral black dog that protects sacred places and is tied to Sirius Black in Harry Potter and the Prisoner of Azkaban.

But beyond the wizarding world, the Grim has deep roots in folklore and urban legends, often depicted as a guardian of cemeteries or a harbinger of consequences for those who dare desecrate sacred spaces.

Grab your flashlight, stay close to the fire, and let’s dive into this tale of sacred duty, respect, and the thin line between the living and the dead.
