Choose the correct form of the verb to complete the sentence with the past participle. De pequeña, yo _______________ con delfines muchas veces.

The sentence needs a past participle construction: the pluperfect is formed with the imperfect of haber plus a past participle. For yo, haber is había, and soñado is the past participle of soñar. Thus, “De pequeña, yo había soñado con delfines muchas veces” is correct. “Habías soñado” goes with tú, while “soñábamos” goes with nosotros and is not a past participle construction.
