Treasure in a dream often symbolizes hidden potential -- a talent, opportunity, or sense of self-worth you haven't fully uncovered yet. Searching without finding it can reflect a reward that still feels out of reach, while discovering it often names a strength in yourself you're just beginning to recognize.
The signification of the conjunction, is not lessened by an aspect; but the aspect is by the conjunction; as having lesser force, than it. - William Lilly (1602.-1681.)
