Alucinar literally means "to hallucinate", but in this song, it's used to describe being completely captivated or mesmerized by someone. It's a much more intense way of saying you're enchanted.
Eslabón Armado sings, "Quiero alucinar contigo" (I want to be blown away with you), expressing a desire to get lost in a dream-like state with his partner. It’s a powerful, poetic word for when someone's presence feels so surreal and amazing that it's like a wonderful hallucination.
This song is all about getting lost in a perfect moment with someone special. The singer wants to escape everything and just focus on this one person, saying, "Olvidemos todo hay que disfrutarnos ahorita" (Let's forget everything, we have to enjoy each other right now). It's a sweet, romantic fantasy where they might just "volaremos hacia el espacio" (fly to space) or walk towards the moon together. He's completely captivated by her, feeling a sense of calm and relaxation that makes him want to leave the "mundo lleno de pura maldad" (world full of pure evil) behind.
The whole vibe is about slowing down and savoring the connection. He talks about dancing slowly while stars shine and getting lost together, maybe in a private room where they can shut the door on the rest of the world. He's so into her that he says, "Tu cuerpo ahorita me tiene alucinado" (Your body right now has me hallucinating). It's a song about that dizzying feeling of new love, where all you want is to be with that person and make the moment last forever.
