Abismo translates to "abyss". It's a strong and evocative word that immediately conjures images of depth and mystery, making it quite memorable.
In the context of the song, the singer expresses a desire to "reencontrar lá no teu doce abismo" (re-encounter myself there in your sweet abyss). This metaphorical use of "abyss" suggests a profound, perhaps overwhelming, connection to another person, where one might lose and then rediscover themselves. It adds a layer of poetic intensity to the romantic theme.
Paula Toller's À Noite Sonhei Contigo ("I Dreamed of You at Night") turns one effortless dream into an argument for letting go. She opens matter-of-fact — "À noite sonhei contigo, e não 'tava dormindo" ("At night I dreamed with you, and I wasn't sleeping") — insisting the dream felt more awake than sleep, and easy: "Sonhei que não fazia o menor esforço, para que te entregasses" ("I dreamed I wasn't making the slightest effort, for you to surrender").
The chorus turns that ease into a small philosophy — "Que lindo que é sonhar... e não te custa nada mais que tempo" ("How beautiful it is to dream... and it costs you nothing more than time") — and sets it against the weight of being awake: "Sofrer com tanta angústia, por coisas tão pequenas" ("To suffer with so much anguish, over such small things"). The wish that closes it is the song's real ache: "Quem dera me livrar pra sempre de mim mesmo, e só me reencontrar lá no teu doce abismo" ("I wish I could free myself forever from myself, and only find myself again there in your sweet abyss").
