Someone tell me what my dreams mean!

After learning about the 5 Stage sleep cycle, I can understand why many people don't remember their dreams - they wake up in a completely different cycle. I love when I can remember my dreams, even though it doesn't happen very often. Although many biologically based theories, such as the Activation-Synthesis Theory and the Neurocognitive Theory, are probably more accurate, I like to believe that Sigmund Freud's Dream Protection Theory has some truth to it as well. I am particularly intrigued by Freund's idea of the manifest content versus the latent content of dreams. The dream itself (manifest content) was to be used to discover the true or hidden meaning (latent content) that the dreamer should realize. The manifest content tends to be very abstract while the latent content is more metaphorical. Some interpretations of dreams can be far-fetched, but some ideas are quite intriguing.
Therapists and psychologists tend to work with their clients to use the manifest content of their dreams to figure out the latent content and then help the client figure out what in their life caused this dream to occur. This video created by Dr. Elligan from minutes 4:15 to 7:00 discusses Freud's Dream Protection Theory in great detail and Dr. Elligan also uses one of his own dreams and interprets it as an example of this theory in action.

After researching Freud's theory more, I am still wondering how dream interpreters can say what a dream represents. Doesn't it depend on each individual person's life experience? How can someone interpret a dream about someone else and claim that there is truth to it? And, how can people be sure they are interpreting their dreams correctly?
