Seeing one of the prophets signifies great fortune, honor, and attainment of what is hoped for.
Ibn Sirin says seeing the major prophets signifies honor and dignity, while seeing the other prophets signifies victory, strength in religion, and fulfilling trusts. Kirmani says seeing a prophet cheerful and smiling signifies honor, effort, and victory.
Ja'far al-Sadiq interprets seeing the prophets through mercy, blessing, honor, high rank, authority, victory, happiness and leadership, strength in Islam, and good and ease in this world and the next. Quarreling with a prophet signifies misfortune and turning away from the Sunnah toward innovation.
Wearing a prophet's garment signifies goodness in religion and worldly life, while seeing oneself as a prophet signifies dying as a martyr.
