I Hope I Am There At The End Of The World

I had this dream,it appeared as if the ocean was getting violent and it looked like there was going to be a tsunami, or something, but this was not happening from the beach or the sea side but from a dam or a resevoir of some sort, some sort of artificial structure built to hold large bodies of salty fresh water.In the dream I was very certain that I had to calm this situation, otherwise lots of people would die, like a natural catastrophe of some sort. In the dream I seemed to be some sort of hero who knew what to do, and that the water from the oceans were a huge threat as these are the last days. This is not the first time I'm getting dreams about large water bodies... The last time I had a dream about the water from the river standing tall towards the sky exposing the river bed instead of lying flat as water is normally known to do. Does any one who analyses dream symbols have any idea as to what this dream could mean? It would be helpful as I have a lot of these recurring dreams that make it harder to get back to sleep,and I keep being unable to concentrate on daily tasks because I keep wondering about how to prevent what happened in the dream on a subconscious level even in my waking life. I used to get a lot of dreams about the end of the world but I'm on schizophrenia medication and that seems to have stopped altogether or gotten slightly lesser.
