Sleepwalking is a song by English rock band Bring Me the Horizon, released in 2013 on their fourth studio album, Sempiternal. The track marked a shift toward a more melodic, electronic-influenced alternative rock sound, with a memorable chorus that helped it become a fan favourite. Over time, short clips of the chorus have circulated on social media and in fan edits, where its anthemic lift fits dramatic moments. Its lasting appeal comes from that blend of emotion, melody and intensity.
