Repetitions occur in the dream as compulsive behavior or as recurring dream symbols. Repetitions, that make us unhappy, Sigmund Freud called neuroses.
If you are dreaming always same dream or a dream series in the same behaviors again and again, same situation or same dream symbols – then this dream says to you, that you should give up your compulsive repetition in daily life.
The dream want to create with this information an awareness of your repeats. If repetition of dreams in short intervals occur, then dreams have always the same meaning and always refers to the same thing. But if between same dreams is larger interval of time, so it will almost always mean something else. Human does not live forever in the same conditions and so are the dreams also refer repeatedly to the new circumstances.
For example: if a perfume retailer dreamed that he had no more nose. Then he gave up his business, because without nose – no smell and he could no longer practice his profession. After his career change he had that dream again. But this time he was caught with forgery and had to flee to a foreign country. This time, meant the loss of the nose, that his face was ugly, he seemed to have lost his face – so he lost his reputation. It is always important to consider the circumstances in the interpretation.
