What dreams mean varies according to experts. Some believe that dreams don't really mean anything, while others argue that they are connected to our thoughts and emotions. Those experts suggest that dreams express our deepest concerns, fears and desires; and if we study them we can understand what's going on in our lives.
On the flipside, some dream researchers believe that dreams aren't necessarily filled with meanings, but instead are mind games about different aspects of our lives or things we see on TV or read about in the papers.
