Dreams are often studied as the unconscious feelings of the sleeping person. For example, dreams about falling show the insecurities and anxiety the dreamer faces.

There are common dream symbols that people use to interpret what their dreams are trying to say. You will have to base their correctness on your specific culture and how much you believe in dream interpretation. You can find more information here: http://www.dreammoods.com/...
