A pregnant woman in a dream usually symbolizes new potential taking shape -- an idea, relationship, or project that's growing but not yet ready to be revealed. The anticipation in the dream can mirror real excitement or real anxiety about what's coming, sometimes both at once. Dreaming of pregnancy, even without any literal connection to it, often just marks a period of quiet, necessary growth.
Conjunction of celestial bodies is a great support that we have to take advantage of. - Picatrix (Andalusia, ~1000.AD)
