The clip comes from a user-generated soundboard upload labeled as a song remix by Tolya Summer, built on the Russian fairy-tale opener 'za gorami, za lesami.' In Russian storytelling that line works like 'once upon a time,' instantly signaling a faraway, magical place, which is why short-video creators adopted it as a framing device. Filed under TikTok trends, it spreads the way most trend sounds do: one edit's storybook transition gets copied, and the familiar phrase becomes shorthand for a distant or dreamy reveal.
