In the dream directory attributed to Ibn Sirin it is stated:
River ï¿½ In a dream, a river represents a noble and a great person. Walking into a river in a dream means befriending or encountering such a person. Drinking from a river in a dream means trials, but if the water is clear, it means enjoying prosperity and a happy life. Jumping from one bank of a river to the other in a dream means escaping from adversities, dispelling distress or anguish, and it means winning victory over one’s enemy. In a dream, a river also denotes travels. Swimming in a river in a dream means working in the government. If the river runs through the streets and markets, and if one sees people bathing in it or taking their ritual ablution in it in one way or another it in a dream, such a river then represents the justice of a ruler. If the river floods the streets, or runs through people’s homes and damages their properties and personal belongings in the dream, then the river represents an unjust ruler, or it could represent an invading army. If a river flows from one’s house and causes no harm to anyone in a dream, it represents one’s good intentions or deeds. Dream Interpreter: Ibn Sirin
The above quotation shows how difficult dream interpretation really is, because the same dream may have different interpretations and we really need an expert holy person to interpret it correctly (which I am not by the way).
