Hi, I'm brand new here too, but I would say that your dreams seem unclear mainly because the clarity is one of the first things you lose with the memory of your dream. I think the most important thing is to try and remember your dreams, go over and over them as soon as you wake from one, and if you really think about it, you will probably see that it actually didn't seem unclear at the time you were dreaming it, only when you woke up. Being able to preserve the vividness is a big challenge, because it slips away so fast. Good luck with it!
