Seeing a valley in your dream can symbolize humility, rest, and security. This dream may carry important messages about various aspects of your life. Understanding the connection between the nature of the valley and your current life situation can help you interpret its meaning. This symbol in your dream might indicate changes, growth, or new possibilities on the horizon.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Valley" (page 458) â resolved via the equivalent "Wadi" entry.
Seeing a ravine or a valley with a dry watercourse in a dream means going on a tiering trip, taking a longjourney, or it could represent an intractable person. Seeing a wadi in a dream denotes good deeds, or making offerings to please God Almighty. A wadi in a dream also represents its dwellers, a tribe from that region, or its plantations. Ifone sees the wadi blossoming with fruit trees, fragrant flowers, a running water course, or if one hears nice words during such a dream, it means that he will rise in station, or mingle with people in power, or receive an appointment in the government, and for a righteous person, it means that miraculous events and blessings will be shown at his hands by God's leave. Seeing a wadi in a dream also means rain, and that the ravine will be filled with rainwater. A wadi in a dream also could represent a prison because of the steep mountains surrounding it and the difficulty in crossing it. Seeing oneself in a wadi floating in the air until one reaches a desired altitude in a dream means working for a powerful person. A wadi in a dream also represents a warrior, a bandit, a highway robber or a lion. If a wadi obstructs one'sjourney in a dream, it may represent a robbery, heavy rain, or having to face a dangerous person. If one is not travelling, then it means distress, adversity, harm, imprisonment, fear, or illness. Crossing a wadi in the wintertime in a dream means escaping from danger. Digging a wadi in a dream means the death of a family member. Falling into a steep wadi in a dream and feeling no pain or incurring no harm from it in a dream means that one will receive a gift from someone in authority or from his superior. Inhabiting a valley with no vegetation in a dream means performing one's pilgrimage to Mecca. To wander aimlessly in a wadi in a dream means writing a poem. (Also see Flying)
