Anestesias comes from the verb 'anestesiar', meaning 'to anesthetize' or 'to numb'. It's a striking and uncommon word to hear in a song, directly borrowed from medical terminology.
In the lyric "Con un besito me anestesias" (With a little kiss, you numb me), Carin Leon paints a vivid picture of a toxic relationship. A simple kiss acts like a drug, temporarily numbing all the pain his partner causes and keeping him stuck in a painful cycle. This clever metaphorical use makes it a truly unforgettable word.
This song is about being completely stuck on someone who is absolutely no good for you. Carin Leon knows this person is trouble, admitting, "Vas a ser mi perdición" [You're going to be my ruin]. But he's powerless against them, especially when they show up in "ese vestido blanco" [that white dress]. The whole song is built on this impossible situation, summed up in the title line: "Te quiero y me miento y ya no puedo estar sin ti" [I love you and I lie to myself and I can't be without you anymore].
He gets brutally honest about how deep the obsession goes. He drinks to think about them, keeps their memory in his wallet, and even says he's "a lo perro oliendo tus miserias" [like a dog sniffing your miseries]. It's a really intense and kind of pathetic image. He knows he's lost himself in this relationship, asking, "¿Por qué me perdí a mí?" [Why did I lose myself?]. But then he admits something wild: "Me encanta verme sufrir" [I love to see myself suffer]. It's a confession that he's addicted to the pain of it all.
