Pasmar means "to be stunned" or "to be dazed", a less common verb that captures a moment of such intense shock or surprise that a person seems almost frozen in place. It carries more drama than a plain word like "surprised".
In the song, the verb is used to describe a feeling so overwhelming that it leaves the singer paralyzed for a moment, unable to react right away, which makes the word fit perfectly into a story about being caught completely off guard.
Have you ever gone through something really tough, something that felt like an "accidente" [accident], and come out stronger on the other side? That's exactly what DLD explores in this song. He starts by admitting, "Ya lo sé / Todo lo que me perdí" [I already know / Everything I lost], and even though someone is there now, he's honest: "Admito que no soy feliz" [I admit I'm not happy]. It's a really vulnerable moment, acknowledging past mistakes and the lingering feelings.
But the song isn't just about regret. It's about transformation. After this "accidente," he sings, "No sé qué pasó pero me hice más fuerte" [I don't know what happened but I became stronger]. He was "pasmado" [stunned] and couldn't look away, but now he's ready to "vuelvo a caminar" [walk again]. It's a powerful message about finding strength after a difficult experience, even if you don't fully understand how it happened. He's moving forward, carrying what he learned: "Pues todo lo que te aprendí / Se queda para siempre" [Because everything I learned from you / Stays forever].
