it depends on what you believe about dreams. personally, I believe that dreaming is your astral body trying to communicate with you, and either warning or reminding you about a specific problem. Or it could just be telling you about your problem and showing you different ways of solving it...only in a very weird code. When you just wake up from sleeping, you can remember dreams most. Try to decipher anything or people in your dreams that might pertain to real life, and figure out what your astral body is trying to tell you.
most people don't exactly notice when they're dreaming. you dream while in REM (rapid eye movement) and you only dream little bits and pieces, though to you it may seem like it's one huge stream of dreams.
Good Luck
