Color: Wherein your dream is in full color rather than monochrome, e.g. reds blues greens and the Sun so bright you cannot stare at it.
Levitation: Wherein you either a) jump off from a great height and land rather than die, or you b) rise from your current position and float and move; either way you begin to move and experiment.
When I was a child (<10 years) and now that I am older (>50 years) I find dreams of continuing renewed interest. My sister has "skating" dreams whereas I have "flying." In both cases, there is a great deal of enhanced freedom. Is that perhaps the definition of adulthood?
