"Lost" by Sinner's Heist & Unknown Brain is a song that delves into the feeling of being lost and unable to move on from a past relationship. The lyrics express the struggle of trying to forget someone who constantly occupies the mind, even in dreams. The phrase "Lucid dreams won't let me rush" suggests that even in the solace of dreaming, the narrator is unable to overcome the emotions tied to their lost love. They cannot escape the memories and thoughts of this person, regardless of the conscious efforts they make. The line "I'm lost and now I can't move through you, you lost me too" reflects a sense of being trapped and unable to progress. Despite feeling lost and abandoned, the narrator still holds onto the pain caused by the other person, indicating that the pain is mutual – "you lost me too." Throughout the song, there is a plea for release from these emotions and a desire to forget, yet the repetition of "Lucid dreams" signifies the recurring, haunting nature of these thoughts. The lyrics imply that time will not heal the wounds, as "Time won't ever let me go" amplifies the everlasting impact that this lost relationship has had. Overall, "Lost" explores the aftermath of a broken relationship and the difficulty of trying to move on when the memories and emotions remain so vivid.
