Dreaming of a river and clear water often symbolizes emotions and the flow of life. The river can represent your journey and the experiences you're going through. Taking out nice rocks from the lake suggests that you are discovering valuable aspects of yourself or your life that may have been hidden or submerged.

The presence of someone who feels like a significant other, even if you can't see them, indicates a connection or bond that is important to you. This person may represent comfort, support, or a deep emotional connection in your waking life.

Overall, this dream may reflect a positive phase in your life where you are uncovering treasures (the rocks) in your emotional landscape, possibly with the support or influence of someone significant. It could be a sign to appreciate the beauty in your relationships and the emotional depth they bring. Consider reflecting on how you feel about your current relationships and what treasures you might be discovering within yourself.
