A marsh in a dream represents your feelings of powerlessness. When you are stuck in a marsh or swamp, it is not always easy to find a way out from it. Similarly, sometimes you are lost facing tough decisions or feeling like there is no way to win, so you give up. You feel powerless with unrealized and pending tasks to accomplish. In this sense, the marsh in the dream may be an indication of the state of being that has left you with many regrets and remains unresolved; perhaps something spiritually, mentally or physically demanding. Look to your recent past experiences to see where you can tackle unresolved matters in your waking life.
