Dream of dolphins

I was sitting on a white dock with family an orange dolphin came up to me allowed me to pet it and then allowed me to ride it. We went down just a little I could see the bottom it was clear with sharks and other marine life. I was told that you could only go in the water if a dolphin invites you cuz if you do without them the sharks and other dolphins would kill you. I felt free it was a short ride but seemed fun and made me happy
