I don't know why it is called that but I picked it because of the aurora which reminds me of Xmas time, I've never seen it but it has reached us here but I missed it, I always wanted to see it and it's very rare to see so I kicked myself.
I think the one I was thinking of was the swimming of whales under the ocean. I kept looking for something with pine cones or Rome in it. lol Very soothing/relaxing to watch and listen to. Much needed in our busy season.
