A dream in which you see the teller that just sitting and do nothing, predicts that you should beware of the losses in the business. If you dream you put into the bank gold bars and coins, then maybe you are too careless. If you get them in the bank, wait for good profit. To dream of a pile of coins and banknotes promises you good luck and a stable position in the society.
Seeing yourself as a banker is a good sing. You are capable to establish well working business and be the king of the empire. Only one thing may prevent you from success is your laziness.
