What is the interpretation of a Catholic woman dreaming of seeing herself in a mosque, with a man dressed in black describing the beginning of creation, light, and darkness, followed by a blind boy carrying an illuminated book?

A good dream is one of the good tidings, and this dream is a great tiding for you. The mosque in a dream symbolizes Islam and monotheism, and the lack of purity within it means incomplete entry into Islam. The Qur’an is the book you saw, and the space between light and darkness represents the struggle between truth and falsehood, and between Islam and polytheism. The Arab youth may symbolize the Prophet Muhammad, peace and blessings be upon him, or a real Arab person you may meet. This dream calls you to embrace Islam, perform ghusl (ritual bath), and then pray in the mosque, just as Thumamah ibn Uthal did after he was a captive in the mosque.
