Wall Climbing

I was climbing a brick wall. The wall was incredibly high and, as it was made of brick, it was almost smooth, with no ridges to grip; it was very hard work.

What does this mean?

Climbing: It is a sign of business prosperity to find yourself climbing, unless the effort proves too great for your strength. Still, even then, it shows some sort of good fortune, though combined with difficulties/If you dream you are climbing upwards, your circumstances in life will improve, or you will marry above your station/The satisfying completion of a hike or climb means you feel proud of a major accomplishment. If, however, you find the climb tiresome, reconsider your expectations-you may have set unrealistic goals
Walls: Dangerous enterprises, unless you climb over them easily, when they betoken business success/Should one stand in your way, you are in danger of doing something you will regret
