I had a dream where I saw major flooding it looked like California I saw there was no water on the ocean where there once was

I just had a dream that there was some event I do not know what but it started that on the news it was showing sharks regurgitating there food like turtles etc there was no explanation something strange and then the next instant my husband and I were in a car or truck it looked like a freeway but I could see the ocean and there was no water just rocks but the water was very high up. There was a man in the dream he talked about 6.5 knotts I do not know what that means he said a year for this when I kept asking him what he meant he dissapeared and then I awoke.

I did have a dream about a year ago where I saw California had a 7.0 earthquake follwed by a 9.0 and in this dream three states were effected by water. I saw this on the front cover of a newspaper in my dream. I do not know what would cause such a huge earthquake or where the epicenter would be to have such tremendous water?
