Blocking the Flood
Scholars have said that seeing oneself blocking a flood from one's house may indicate resisting an enemy and preventing them from harming one's family or property. Ibn Sirin also mentioned in interpreting a dream of gutters flowing without rain that it might signify sedition and unlawful money. Gutters can also represent mouths, necks, or eyes, and perhaps provisions.
