What does this dream mean?

I had this dream that I was in the middle of the ocean, freezing to death. I started drowning, and i then started praying. A bubble surrounded me so that i could breath. I saw, from my bubble space all kinds of marine life. One of the biggest things i remember seeing is a hunchback whale came up beside me; it's eye was huge! and watching me. Later on in my dream i could see a couple that were stranded in the ocean and they were surrounded by sharks. My bubble floated up to the surface and i told them to get in the bubble with me. So now the couple were with me under the ocean, and we were hoping to drift along to land soon because we were worried about dieing of thirst. then i woke up.
