what does my dream means bridge

I was under a bridge with friends. We were seeking shelter from a gigantic, majestic looking dragon that was just flying about the city, nothing else. It wasn't a fairytale type dragon. More of a chinese-like. After awhile it would dive into the water beside us and cause huge tidal waves, sending many of us into the water. I think someone died. I woke up right after thesecond tidal wave, when i went under.
