Partial early morning dream

I dreamed that I was swimming in the Dead Sea and there was a place next to the shore that was so deep that I wouldn't have been able to see the bottom even if there was no water. Some people I was with had scuba gear and were diving to the bottom and looking around. I was terrified and didn't want to do it. Then somebody came over and said something about seeing a city down there and then three of the people I was with suddenly developed blue scales over their faces, and they grew scuba gear that fit over their mouths and eyes and then the three of them shot off into the sky like a blue flame, intertwining with each other. Then I did want to go down and look in the deep water, but then it was too late. So instead, I got out of the water and walked to the cafeteria with a little girl.
