Dreaming about ocean animals in dark swimming pools can symbolize feelings of confinement or being surrounded by emotions that are difficult to navigate. The shift to a light blue water environment suggests a change in your emotional state or perspective. Light blue often represents tranquility, peace, and clarity.

The fast stream connecting to the pool may indicate a flow of new experiences or changes that are influencing your current emotional state. It could symbolize the movement of thoughts or feelings that are being introduced into your life, possibly bringing about a sense of urgency or excitement.

Throwing things in and near the pool might represent your desire to experiment or take risks in your waking life. It can also reflect an urge to release something or to see how different elements of your life interact with each other.

Consider how you felt during the dream and any specific ocean animals that appeared, as these details can provide further insight into your personal associations and the emotions you may be processing. Overall, this dream seems to encourage you to embrace change and explore new emotional waters with a sense of curiosity and openness.
