A tsunami can indicate a tremendous and fundamental change in you. Most people now know that tsunamis are caused by massive earth changes under the sea. These changes are part of the natural order, and often show themselves to people in their dreams. So they can be understood as an expression of our personal adaptation to enormous changes. They can wash away most of the beliefs, social structures we have built or held onto as important. Yet if we are not afraid of change and the forces that we are actually involved in, then we can find enormous power and force within us.
Remember that tsunamis are dangerous in waking life, but are the expression of your inner life in dreams. They are not dangerous and need not be avoided or run from while asleep. Meeting a tsunami is saying that some tremendous change has happened deep in you and in the world. Tsunamis are caused by earthquakes on the sea bed. So many people are dreaming about them at the moment because of the enormous change going on around us and within us. So learn to face them without fear and be ready to meet change in your life and in your family.
