Why do we dream at all..?..Is it some natural mechanism inbuilt within us to relieve excess stress and pain ..?..Or there is some hidden msg , providing us some tacit hint..
         I guess lots of research have gone into it, trying to fathom out its meaning, its need. A whole lot of people claim to read your dreams.. My belief is that we always dream for  things which are possible.Ya, it does happen that most of the time, you have weird dreams, something which appear meaningless and strange, yet I believe there is always an element of possibility..I can only summarise it in these words :......"Dreams come true, without that possibility, nature would not incite us to have them"...
