The presence of Mercury in your dream is often seen as a symbol of authoritative figures, writers, and leaders. Dreaming of Mercury may indicate challenges or adversities in your life. It can also suggest a desire for travel or new experiences. Through this dream, you might find yourself reflecting on various aspects of your life, particularly regarding your social relationships and your connection to authority.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Mercuryl" (page 275).
The planet Mercury in a dream represents people of authority, writers, commanders, secretary of state, minister, traveling from one country to another, distress, adversities, or fights. If in wakefulness the Moon and Mercury are appearing simultaneously in the skies, then all dreams will be false and one may have to face lies, poverty, scary news, murders, or robberies. The planet Mercury in a dream also represents a policeman. (Also see Heavens) Mercur y2:(Quicksilver) In a dream, mercury means a project, or an intention that will not be brought to completion. If one sees himself giving mercury to someone, or if he holds it in his hand in a dream, it means that he fails his promises. It also means that he disinclines in his religious practices, follows his own mind and desire, or it could mean that he is a hoax, a betraying person, or a treacherous person. Ifhe eats it in a dream, it means that one of his children will grow to be one who fails his promises.
Note: Islamic dream interpretation depends on the dreamer's circumstances and state. This is a general guide drawn directly from the source book.
