Stars in a dream usually point to guidance and aspiration -- a distant goal you're orienting yourself by, even if you can't yet see the whole path there. Countless stars filling the sky can reflect a hopeful sense of possibility, while a single, hard-to-find star may mirror a direction you're still searching for.
Whosoever contendeth with another & overcomes when the significators are in signs bicorporeal, gets a great victory; if overcome, looseth much; for then the good or evil is doubled. - William Lilly (1602.-1681.)
