As per Hindu tradition, seeing moon in dreams is believed to usher in positive change. Generally seeing a moon in dream means the stature of the person will increase in family, society and at the workplace. Seeing Crescent moon is interpreted as hope. Full moon, or purna Chandra, means improvement in health or new love and romance.
Clouds gathering over moon is a sign of some trouble or unexpected failures and disappointments.
Clouds moving away and sighting the moon clearly is seen as change in fortune.
