The quoted lines express a strong refusal to conform to someone else's narrative or emotional turmoil, emphasizing the speaker's desire for autonomy. The use of "locked into your head" suggests that the speaker feels trapped by another's interpretation or expectations, and they are resolutely rejecting this role. It highlights a struggle against being used as a pawn in someone else's story, portraying a deep distrust for the motives of the other person.

Furthermore, the phrase "the hell with your fiction" conveys a frustration with insincerity and manipulation. The speaker prioritizes their own truth and experience over participating in an artificial storyline that someone else has created. This rejection serves as a powerful affirmation of self-identity and the importance of personal agency, indicating that the speaker values their independence and authenticity above all.
