The Channel
Interpreters have said that the irrigation ditch (ساقية) in a dream has various interpretations; its abnormal flow or flow with blood may indicate marriage of a family member to someone else or marital problems. A blocked house channel can symbolize a servant's pregnancy, a wife's disobedience, obstacles in livelihood, marriage, or travel, or possibly a health issue. A well-flowing ditch, especially through homes, suggests a good life. Conversely, an overflowing or dirty ditch may symbolize worries and sorrows, while cleaning it indicates healing. Waterwheels (نواعير) might refer to a trustworthy servant or the cycles of trade and changing circumstances.
