In general:

Merchant embodies material or spiritual values ​​and profits, and sometimes greed and selfishness. The individual meaning of dream depends on the circumstances.

Psychologically:

Merchant symbolizes the exchange of values ​​between people. The possession of the merchant may give an indication of the “mental reserves” of the dreamer (his talents development would be promising). He is also the agent who will guide our spiritual “purchasing power” on the right merchandise in the mental deficiency resolves by acting. Often we are merchant in dreams, because we want to do something for us by our own initiative. Further information arising from interpretation of visible merchandise in the dream .
