Dear Christians ,What can be the meaning of the most terrible dream I saw on April 24,2008,at about 3:30 A.M?

I have never experienced such a horrible and terrible dream so far in my life.In the dream I saw millions & millions of fat elphants ( young and old including the baby ones ) coming down from the North marching towards the South. They were in innumarable gangs occupying all areas of the plains destroying all agricultural forms and fields .There was no place unoccupied by the gang elephants .In order to escape from the elphants we some people were travelling in a 4 wheeler ( Jeep ).Since all roads were too fully occupied by the gang elephants, we suffered a lot, And in some places the driver applied the reverese gear and drove fast backward to escape from being caught by the elaphants . Since the van was useless ,we all began to run across the muddy corn fields where too was no safety for us.My wife was holding our eldest son and I was holding our 1 year old daughter . In great horror we were running here & there unsafe . It was dusk. We were afraid that we may hit at the elephants.
