Wall

From my viewpoint, this dream means your being "blocked." A wall may represent an obstacle that prevents you from attaining what you want.
This is a dream of something in your life that is holding you back or blocking you from something you want as well. When you dream of a wall it can be a famous wall like the Berlin Wall or the Great Wall of China. Or, more simply it can also be a simple blockade in front of you or a huge stone wall around your property. Walls can come in many different forms in a dream and the significance of them, their placement, and what they are made out of is what has the biggest influence on your dream.
