In an old apartment building, where echoes of the past echo in the darkness, a chilling legend is hidden: the story of the Phantom Ankle, an invisible entity that lurks in the shadows, waiting for the right moment to manifest its terrifying presence. A young man, visiting his friend's apartment, wakes up in the night with a feeling of paralysis and terror. Something cold and powerful grabs his ankle, shaking him with inhuman force. Darkness envelops him, preventing him from moving or screaming. The experience, brief but intense, leaves him with a deep sense of vulnerability and fear.
