Dream About Mermaid Living Alone Ocean Shark Swimming

I had a dream that felt like it lasted a few weeks. It was beautiful and vivid. It mainly took place at night, so it was always dark. In this dream I was a Mermaid and I lived alone. I had a house that was on land, surrounded by a pool on all sides. The house was the only one secluded on an island. It’s basement was octagon shaped, empty, every wall was glass so you could see into the water surrounding the house, like an aquarium. The only light coming in the glass room was a bright blue glow on all sides illuminating from the pool lights in the water surrounding the home. I was alone here, it was night, and I had a huge hammerhead shark that lived in this pool and would just swim in circles around my house. I would sometimes sit in the middle of the glass room on the floor, and watch the lone shark swim in silence. Again with only light being the soft blue glow. Sometimes I would actually swim with the shark as a mermaid. It was peaceful, empty and just the shark and I. And then the dream would cut away to a very different scene. In this scene I would be in the middle of the ocean, a few meters from the surface, absolutely nothing around me, and I could see myself in a 3rd person view. There was sun light shining through the water, I was still a mermaid, and I was just floating still, not moving, underwater, and on my back. All I could hear was the static sound of water around me, and an occasional sound of a whale far in the distance. It felt warm and quiet.
