Dreaming that you stepped on shit, or were attacked by shit, or got dirty by shit, is an auspicious dream, which means that you will have a fortune in the near future, you will get everything you want, and everything will be smooth.
It is rare to dream that shit stains yourself;
I dreamed that I was stained with shit and urine, suggesting that there would be an unexpected income in the future, but washing again means that although I have money, I haven't kept it!
