Have you ever been so heartbroken that you just wish you could disappear? That's exactly what Santa RM is singing about in "Desaparecer." He's stuck in a cycle of seeing his ex everywhere, especially when he closes his eyes, and it's driving him crazy. He keeps asking, "dime por qué yo no sé qué hacer / si cierro mis ojos si te vuelvo a ver / quisiera desaparecer" [tell me why I don't know what to do / if I close my eyes and see you again / I wish I could disappear].
He even dreams about her, chasing her, only to wake up just as he's about to reach her. It's a painful reminder that he needs to let go, even though his heart screams her name. He wants to disappear from her memories and stop waiting for her songs, because her kisses and hugs were his worst addiction. He feels like an astronaut lost in space, wanting to go back to when she was his whole universe, but he knows it's not healthy. He promised to do anything to see her happy, even if it meant he wasn't in her life, and now he just wants the pain to stop.
