I've dreamed about flying before, 
but this feels even better.
حلمتُ بالطيران قبلاً، لكنّ هذا الشعور يعلو ذلك
Ich habe immer vom Fliegen geträumt,
aber das ist ja noch viel besser als gedacht.
Alguna vez soñé que volaba,
Alguna vez soñé que volaba,
J’avais déjà rêvé que je volais,
mais là…
Mi è capitato di sognare di volare,
ma è ancora meglio di quanto pensassi.
Eu já sonhei em voar pelo céu,
mas o que eu estou sentindo agora...
Мне снилось, как я летаю, но это
 чувство ни с чем не сравнить.
