To see a stain in your dream, indicates a superficial and reversible mistake in your life. Consider and analyze the substance and color of the stain and the location of the stain itself. If you cannot remove the stain, then it represents guilt or your unwillingness to forgive and forget.
To see stain on your hands, or clothing, while dreaming, foretells that trouble over small matters will assail you. To see a stain on the garments of others, or on their flesh, foretells that some person will betray you.
