Having been subjected to Freud in my psychology classes ... I believe it is completely valid to say that the man should have been tarred and feathered. And has no business coming anywhere near my dreaming mind. However ... I do believe that dreams are a unique conversation, and if you know the language you are precieving then it has the potential to broaden your own scope of vision and understanding. The hard part is understanding what you see.
For instance, there is a dream divination that I've done that produces surprising things. Its a simple Yes or No divination with black & white symbology. For 3 nights you literally watch your dreams and look for the predominant colour ... your choice as to whether you want to believe it is a message from the gods or your own intuition speaking.
