Swimming with skeletons

This is another dream from a long way back. Maybe even a few years by now.
And of course it took place in the Arctic.
I found myself swimming in a vast body of water.
The water was cold and I was tired.
I then found myself climbing upon a skeleton of what I think was a blue whale.
It was obviously enormous.
The whale skeleton was floating in the water.
I was sitting at the top of the skull of the skeleton, resting from swimming the Arctic waters.
There were more giant skeletons bobbing up and down for miles.
It was creepy.
But interesting.
I've always meant to draw the image. I'll put that on my creative to do list.
