I have loads of dreams that I tend to consider pointless.
After I've written them down though I can re read them and sift little things out of them that gives me something to think over.
Even a boring old dream of walking for miles on an endless stretch of never ending road has a deeper meaning. I think you can find meaning in any dream if you sit and chew it over.

Start really looking into your dreams. If you start paying more attention to them the more apt you'll be to one time stop in mid dream and think, Hey, I might be dreaming.

Good luck and keep trying.
And stay positive. It makes a world of difference.
