"Water is life's mater and matrix, mother and medium.
There is no life without water." - Alber Szent-Qyorgyi

The symbolism of water has a universal under tone of  purity and fertility.

The theme of water in our dreams symbolises our emotional state. whether the water is clean, dirty, flowing of rushing can reflect the way we feel and is a way for our sub concious to tell us how we are feeling while we sleep.
The fact that water has this kind of symbol to people shows that the power of water has a major impact in the reflection of our emotions and the way we feel.
