Lighthouse keeper
The solitary tender of the light — a person whose job is to keep one signal burning for strangers at sea.
A lighthouse keeper in a dream is the dream's image of a person whose entire vocation is to keep a single useful signal alive on behalf of people they will never meet. The keeper does not steer the ships; the keeper tends the light, and the light does the work. The dream brings the keeper when something in your life — a quiet commitment to honesty, a long parental vigilance, a small public service kept up without recognition — is currently being performed in that solitary, faithful mode. A keeper climbing the stairs to trim the wick is the dream affirming the steady tending. A keeper asleep at the foot of the tower while the light has gone out is the dream noting that the signal others depend on has failed, and the failure was unwitnessed because the post was, by its nature, alone.
