A boil in a dream is wealth proportional to its size. If it bursts and pus comes out, the wealth is gone. If blood comes out, it is unlawful money.

A boil indicates worry and grief. The exit of its contents indicates the removal of worry.

A boil is interpreted as wealth. Whoever sees many boils on his body will gain abundant wealth.
