Seeing a tank or reservoir in your dream typically symbolizes your personal life or relationships. It may represent your sense of security, partner, or family members. If the tank contains water, it suggests emotions or hidden information. This dream could reflect your desire to uncover deeper truths about your relationships or acquaintances.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Tank" (page 428) â resolved via the equivalent "Cistern" entry.
In a dream, a water cistern represents a pouch, a safe, a box, a coffer, a partner, one's wife, a son, or knowing people's personal secrets. Ifthe oil cistern is filled with water in the dream, it means stagnation of any of the above. Ifone sees a water cistern filled with oil in a dream, then it means prosperity. The cistern of a fellowship house, a khanakah or a mosque in a dream represents its Imam or its supervising spiritual teacher or the caretaker and guard of the property. Ifone sees the water cistern of the house sitting in an unsuitable place in that house in a dream, it represents the spirit of a jinni who pursues such a person or who may haunt his house. If one sees a well being used as a cistern in his house in a dream, it denotes that the dwellers of that house are of the middle class, or it could mean that the water of that house is salty or non potable. If one sees the cistern filled with butter or honey or milk in a dream, it means that one's wife is pregnant, or it could mean prosperity for that family. If the family of such a house is thirsty in the dream, and if the cistern is filled with other than water, then it means that they owe alms tax and must pay the necessary charity on their assets, or it could mean that such a family has turned its back to God's path and preferred worldly gains instead, or that they have a knowledge that they do not practice, or it could mean shortage of rain in that locality that necessitates spending money on God's path. A cistern in a dream also could represent a protective shield or a pocket, one's dignity, blessings or attaining a respectable rank or dispelling difficulties. However, this interpre tation can only apply for those who use a cistern or a similar water container or a water dispenser and in their case, it also could mean peace and protection from any fears.
