Song meaning of Someone Else (Underoath Remix) by Rezz & Grabbitz

The song "Someone Else" by Rezz & Grabbitz explores the theme of discovering the true nature of a person after being in a relationship with them. The lyrics talk about waking up in a bed that the person used to share, feeling their presence, but not seeing their face. It suggests a sense of loss and longing for the past when the relationship was still intact.

The chorus repeats the question "Who are you when I'm not looking?" which implies that the person being referred to is different when not being watched or observed. This highlights a sense of deception and betrayal, where the person portrayed themselves differently in front of the protagonist but showed their true colors once they were alone.

The line "Despite those lies that took me" suggests that the protagonist was taken advantage of or manipulated with false information or promises. This emphasizes the feeling of being deceived and not truly knowing the person they were in a relationship with.

Overall, the song expresses the experience of realizing that someone you thought you knew and could trust is not who they appeared to be and the pain and confusion that comes with that discovery. It reflects on the contrasts between the person's actions in public and private, ultimately leaving the protagonist questioning their own judgment and understanding of the relationship.
