Seeing a crown in your dream may signify the arrival of new success and honor in your life. It represents your ambitions, power, and social status. If you wear a crown in the dream, it could indicate the birth of a child, a move to a new city, or new opportunities on the horizon. Significant changes may be coming in your life that will help improve both your personal and professional circumstances.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Crown" (page 104).
For a Muslim, a crown in a dream represents the Holy Qur'an, knowledge, prosperity or marriage to a wealthy woman. Wearing a crown in a dream means begetting a son, moving into a new city or forcing an enemy to retreat. Ifa woman sees herself wearing a crown in a dream, it means marriage to a noble and a high ranking person. If she is married and pregnant, it means she will beget a son. If a prisoner sees himself wearing a crown in a dream, it means that he will be released fromjail and regain his dignity. Wearing a crown studded or inlaid with gems in a dream is better than wearing a plain golden crown. Wearing a golden crown in a dream is also a bad omen. If a widow sees herself wearing a crown studded with gems in a dream, it means marriage to a wealthy person from another country. If the crown is made of gold in the dream, it means that she will marry an old man whom she will shortly inherit. If an unjust ruler sees himself wearing a golden crown in a dream, it means that he will lose his eyesight, while if he sees himself wearing a golden crown inlaid with gems in the dream, it means establishing trading interests with a foreign country. If a woman's crown is stolen in a dream, it means the death of her husband. (Also see Turban)
