The dream of a button is often seen as a symbol of protection and honor. It may also represent a deal, money, or gain in your life, especially if the button is silver or gold. The connection between the button and the buttonhole reflects important relationships and a sense of security in your life. If you see a button in your dream, it indicates that you are striving to protect your interests.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Button" (page 64).
A button in a dream represents protection, guarding one's honor, ajust contract, money, or profits particularly if the button is made of silver or gold. A button and a buttonhole in a dream also represents a man and a woman. If an unwed person sees himself buttoning a shirt in a dream, it means that he will get married, or that he will play an important role in uniting two people, or to bring peace between two partners, or that he will revive an old and a forsaken project. Tying one's buttons in a dream means getting married, or going through difficult financial circumstances. Wearing a buttoned shirt in a dream means experiencing tight circumstances, or reuniting with a traveller returning home, or marriage of an unmarried person. (Also see Clothing)
