Derritió is the past tense of derretir, meaning "to melt". It's a powerfully visual word that creates a surreal, dreamlike image.
In the song, Cerati sings "Mira el reloj, se derritió" ("Look at the clock, it melted"), famously evoking the melting clocks of surrealist painter Salvador Dalí. This striking metaphor perfectly captures the song's theme of time and perception bending, just like in a real déjà vu.
Have you ever had that strange feeling that you've lived a moment before? Gustavo Cerati's "Deja Vu" is all about that exact sensation. He describes it as going "de fuego en fuego hipnotizándonos" [from fire to fire, hypnotizing ourselves], a cycle of intense moments that seem to repeat. The song suggests this isn't a memory, but something more like a dream, with "Similitudes que soñás / Lugares que no existen" [Similarities that you dream of / Places that don't exist]. It's a glitch in reality, what he calls "Errores ópticos del tiempo y de la luz" [Optical errors of time and light].
The feeling gets stronger as he describes the desperate wish to freeze a perfect moment: "Tanto pediste retener / Ese momento de placer" [You asked so much to hold on / To that moment of pleasure]. This desire seems to bend time itself. The song even points to itself, saying "Esta canción ya se escribió" [This song has already been written], making you feel like you're in a loop. The best line is a direct reference to a famous surrealist painting: "Mira el reloj, se derritió" [Look at the clock, it melted]. It's a fantastic image for how time feels when it stops making sense.
