In a dream, pus means a continuous source of money. Puss-filled sore in a dream represents the growing of one’s savings, a show of prosperity, a monthly pay off to a band of criminals, or it could mean slander.
Anything that runs from one’s body such as puss, purulence, sperms, etcetera, in a dream means unlawful money.
If one sees pus coming out of a sore or a boil in a dream, then it represents the male or the female sexual organs.
