Seeing land in a dream is generally considered a symbol of wealth and prosperity. It may indicate the arrival of new opportunities and abundance in your life, as land serves as a source of sustenance for a city. This dream can also signify stored resources in your life, such as grains, fruits, or vegetables. Overall, it points towards future growth and financial success.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Estate" (page 144).
In a dream, a farmland represents wealth and benefits, for cities live from the produce of a farmland. A farmland in a dream also represents stored grains or fruits or vegetables. Anything that affects the farmland, such as drought, inundation, diseases or a fire in a dream will manifest in people's life in the cities. A farmland in a dream also may represents one's livelihood and earnings, a patient and a helping wife, or a hard-working and a patient husband. Ifone sees a blossoming farmland in his dream, it means blessings, growth and profits from his work. A farmland in a dream also means wasting one's life in useless endeavors, or it could mean heedlessness, lack of comfort, pleasure in one's life or neglecting to seek knowledge while occupying oneself in pursuing mundane objectives. (Also see Farm)
