Director: Oh Choong-hwan
What if the dreams that haunt you at night could actually save a life the next morning? That question sits at the center of "While You Were Sleeping", a South Korean series that blends romance, fantasy, and quiet suspense into a single unhurried story.
What is While You Were Sleeping about?
Nam Hong-joo works an ordinary job while carrying an extraordinary and unsettling gift: her dreams sometimes show accidents before they happen. When she crosses paths with Jung Jae-chan, a determined prosecutor, the two are drawn into a shared effort to prevent the futures her visions reveal from coming true. Their growing bond unfolds against the backdrop of Jae-chan's demanding cases and Hong-joo's attempts to understand why she sees what she sees, with each episode weighing small daily choices against the possibility of altering fate itself.
Cast & crew
Bae Suzy plays Nam Hong-joo with a grounded warmth that keeps the show's fantasy premise feeling personal rather than gimmicky, while Lee Jong-suk brings a measured intensity to Jung Jae-chan's sense of duty. Jung Hae-in appears in a key supporting role that adds emotional weight to the central trio, and the wider ensemble, including Lee Sang-yeob and Park Jin-joo, fills out a cast that treats the series' premise with sincerity rather than melodrama.
Context & significance
Directed by Oh Choong-hwan, the series arrived in the middle of a wave of Korean dramas mixing procedural elements with fantasy and romance, a combination that has become one of the industry's most reliable exports. Its episodes run at a shorter, tighter length than many Western dramas, favoring emotional beats and character detail over sprawling plot arcs. "While You Were Sleeping" has earned strong audience ratings for how naturally it folds a supernatural premise into everyday settings like courtrooms, apartments, and late-night streets.
Where & how to watch
"While You Were Sleeping" streams on K-Time with a Persian dub, letting Farsi-speaking audiences follow the story's dialogue-heavy scenes without relying on subtitles. Signing in with a K-Time account is required to watch, though anyone can read about the series here first. K-Time's Farsi interface is built with Korean drama fans among the diaspora in mind, making it simple to find and continue watching episode by episode.
