Sleep and Consciousness
Metaphoric Magic in Dreams
Dreams speak to us albeit it is in a different language. The language is metaphor. While awake we might use the metaphor rose to refer to rosy cheeks while in dreams that rose may be thorny and may refer to Rosie, someone you work with who has a thorny personality.
Therefore the language of our "un"consciousness in sleep can be difficult to understand. Metaphors used in dreams are often idiosyncratic and personal but it is a language you can learn that is somewhat culturally specific. If you were raised in a culture where from day one you were told that if you dream about a white Volkswagens it meant you would get a job. So that if you got a job you'd be sure to dream about a white Volkswagen. Unfortunately most of us are not taught these keys to our inner life thus we are left to our own devices in interpreting our dream metaphors.
