The meaning of multiplicity / variety in dream | Dream Interpretation
If such symbols appear frequently in your dreams, like a street full of water puddles, for instance, or a sky filled with birds of the same kind, it is thought to be a sign of extreme distractions and psychological splitting.
If such dreams are common, it would be a good idea to see a psychologist.
Multiplicity is the essential characteristic of all life events that register in the unconscious—the deeper in the unconscious, the more pronounced the multiplicity.
It is connected to the sympathetic nervous system, where whatever is happening is telegraphed to every cell in the body. Multiplicity has a destructive connotation, because it dissolves the unity of consciousness, occurring often where there is a conflict between the ego, the many different Ts, and influences in the environment. This dream may also point to conflicts and prejudices that are a hindrance.
According to the theorist Gurdjieff, the person who is not free always depends on many egos, and they make themselves known through such dreams. Other people suggest that the many egos of a person are what bring out his or her creative potential.
This dream often occurs during illnesses that are part physical and part psychological—delirium tremens, for example, where hallucinations involving many Mice are not uncommon.
However, multiplicity might also point to an early stage of a new awareness.
According to Freud, the frequency, or the accumulation, of symbols or facts in a dream indicates that they are real and will also appear during waking hours.
