I dreamnt that hay was coming out of my skin. It was a rich yellow color.

It means that you had a dream. Nothing more, nothing less.

I had a dream onetime that superman crashed into my backyard, he died and then became a snowman. I'd like to see someone figure that one out. Like J_9 said, it's a dream. I might even suggest that you look into how your brain creates dreams... it'll probably make you not take them so seriously.
