Killer waves and the surfers in Hawaii?

This dream was short and I should have blogged it last week when I had it. In the dream I was at the beach, and I think it was Hawaii. There were a lot of people at the beach and many surfers out in the water surfing. All seemed well but then the extremely large rouge waves started coming in unexpectedly and hard, almost like a Tsunami but not as bad, though of course still very bad! It started wiping out, and I mean that in a dead sense, many of the surfers. The dream was very strange and quick. It seemed like Hawaii because it was a tourist type place and one that was usually calm and known for it's perfect weather. I think it may have taken out many people who were also just relaxing and down by the water.
