A lake is a contained body of water, reflecting your emotional state in a space that feels safer than an open sea. Still, clear water points to inner peace and honest self-reflection. Murky water signals confusion or feelings you have let sit untended. A lake that changes depth may reflect emotional states that shift without obvious cause. This dream asks you to look at your reflection honestly and to check whether your emotional waters are being kept clear or left to grow stagnant from neglect.
