Whether it is a leaky pipe or a bottle of soda, any type of a leak is usually a waste of energy and resources.
If you are dreaming about leaks, you may want to consider where you are wasting energy and resources ( be it in your daily life, emotional life or thinking).
Additionally, look carefully at the entire dream and see if information is being “leaked” from the unconscious to the conscious.
The leaking water may represent emotions, thoughts, or insights entering slowly into the conscious experience of the dreamer.
To dream of seeing a leak in anything, usually signifies loss and troubles.
