I have been plagued by dreams about the end of the world since I was 12. Typically, the world is "ending" by a violent storm- (the entire sky is dark, once God was evening perched among the trees, striking sinners with lightening bolts !!).
I also have dreams about death ( of other people who I do not know) and the dreams are quite graphic at times.
I use to write down my dreams on a piece of paper after I awoke, but it became too often.
