Descifrar means "to decipher" or "to unravel". It's a less common verb that evokes a sense of mystery and deep understanding.
In the song, the singer expresses a desire to "descifrar el sentido de tus sueños" (decipher the meaning of your dreams). This line beautifully captures the longing to intimately understand another person's inner world, making it a captivating and unique word choice.
Amaral open "Mi Alma Perdida" like a toast before a bad decision: "Dame una corona más / Que esta noche yo quiero perder" ("Give me one more crown / Because tonight I want to lose"), a woman choosing to lose her composure on purpose. What follows reads like a confession of secret devotion — sitting unseen, listening in the dark, decoding someone's dreams, "Protegerte de noche / A los pies de tu cama" ("Protect you at night / At the foot of your bed"). It's intimate to the point of unease, and the song names that fantasy outright: "En poderes paranormales / De heroína de cómic" ("In paranormal powers / Of a comic-book heroine").
The turn comes when watching stops being enough: "Y me atrevo a acercarme hasta ti / Soltarte a la cara la verdad" ("And I dare to come close to you / To tell you the truth to your face"). Whatever she risks by saying it, she walks out ready to give everything — "Te daré mi corazón / Te daré mi vida / Te daré mi alma perdida" ("I'll give you my heart / I'll give you my life / I'll give you my lost soul"). By the time that chorus repeats itself into the fade, it has stopped sounding like a plea and started sounding like a decision already made.
