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.
In matters of secrecy, let not the Moon be combust, but going from combustion. - William Lilly (1602.-1681.)
