À quoi rêve une jeune fille is very underrated in my opinion and I really love this one.
Not only it is so beautiful but also the meaning of the song is closely related to how I discovered Alizée.
The song deals with the topic of suicidal tendencies and thoughts. And that is exactly how I discovered Alizée. As I wrote in other thread, I discovered Alizée when I had depression and suicidal thoughts and my discovery of her led me to recover from all of that.
