Uncle Unknown is a YouTube horror anthology series that feels like a collection of lost, cursed videotapes from a forgotten era. Each episode presents a new, unsettling story, often using a found-footage or analog horror style to create a convincing sense of realism. The mysterious host, known only as "Uncle," introduces these dark tales, which masterfully build psychological dread and creeping unease rather than relying on cheap jump scares. From strange public access broadcasts about alternate dimensions to disturbing home videos capturing supernatural events, the show creates a uniquely chilling atmosphere that will stick with you long after watching. The original series has ended, but sign up for a reminder just in case it returns. It is essential viewing for fans of internet-based horror.
