Déréalisation is a psychological term that refers to a feeling of detachment from one's surroundings, as if the world is unreal or dreamlike. It's a powerful and evocative word that is also the title of the song.
In the context of the lyrics, Zélie uses this word to describe a profound sense of disconnection from her own life and reality, questioning what is real and what is not. This makes it a unique and central theme of the song, offering a deeper insight into the artist's emotional state.
Have you ever felt like you're just floating above your own life, watching it happen without really being in it? That's the feeling Zélie explores in "Déréalisation." She talks about a time when "la nuit noire pouvait durer tout le jour" [the dark night could last all day], describing depression as a "couche-tard que j'ai croisé sur mon parcours" [late sleeper I met on my path]. It's like she's lost her grip on reality, saying things like "C'est moi ou je plane juste au-dessus?" [Is it me or am I just floating above?]
She's searching for her "vrai vie" [real life], the one that never disappointed her. It's a powerful look at feeling disconnected, where even trying to understand pain becomes too much. Zélie sings, "J'ai perdu même mes yeux au moment d'sauter" [I even lost my eyes at the moment of jumping], showing just how disorienting this feeling can be. She doesn't want this reality, this "désert" [desert], and she just wants to find her true self again.
