Dreams?!?

Okay so this may sound crazy but...
First off I have really HORRIBLE vision. I can't see literally 5 inches from my face without the help of contacts or glasses so it's safe to say I cannot function without either or. I have ALWAYS had blurry dreams.. As if I don't have my contacts or glasses on? I was wondering if any of you had a suggestion or may know why this happens to me? Is it because of my bad eyesight? Or what??
