A brightly shining sun is one of the best lucky dreams, symbolizing honor, success, and health. The sun shining directly on you means gaining high status or honor. Two suns rising predicts the appearance of a benefactor or great luck. A disappearing sun or solar eclipse warns of trouble for those above you.
Natural phenomena in a dream like "Sun Dream" are traditionally read as symbols of emotional flow or a major life turning point. Modern psychology often connects such large-scale imagery to feelings about a recent change that felt beyond your control.
