Does the daughter's vision of true and beautiful dreams, and the affliction of whoever scolds or taunts her with the same thing happening to him, indicate that she has a high status with Allah and that she is committed and obedient?

The effects of piety are summarized in that it has worldly and otherworldly fruits. The true vision of a believer is considered a part of prophecy. People, concerning visions, are of three ranks: prophets, and all their visions are true; the righteous, and truthfulness largely predominates their visions; and everyone else, whose visions contain both truth and jumbled dreams. The truthfulness of your daughter's visions is not proof of her status with Allah; rather, her commitment and obedience are the proof.
