Tsunami Warning - Reality Dream 2

To dream about Tsunami....well I thought it was just an illusion...ever since 2009 Fiji was predicted to be a target destination for the tsunami after major earthquakes in Chille and others. Before these tsunami warnings - I had dreams 2 weeks before the event...to be precise a total of 4 dreams of which all became reality.
These dreams as I have mentioned in the earlier posts.....it seems so real that it woke me up and the time was early in the morning like 3.30am or 4am.
In the dreams, I could see people running towards the high grounds as the waves from the sea started rising which later formed a tsunami. I was also running up the hill and could see it coming towards me but once I have reached the top...I was safe...at first it was a funny topic in talanoa sessions with my friends and families but when the reoccuring dreams made everyone realise that I was truly given the gift of seeing events in my dreams that later becomes real - still I had to know how and why?
