Heel
The back of the foot — the bone that takes the first impact of every step.
A heel in a dream is the dream's image of the bone that takes the first impact of every step. The heel is unremarkable when it works and impossible to ignore when it does not. The dream brings the heel when something in your life — a long walk through difficulty, a routine that requires repeated impact, a daily commute that is wearing on the body — has reached the part of you that absorbs the most. A heel callused and intact is the dream affirming that the impact has built appropriate protection. A heel blistered or cracked is the dream noting that the route has finally exceeded what the basic foot can carry without damage.
