A beautiful, large, white swan

I had an interesting dream last night.

I was diving in a cave in the middle of the night. The water was turquoise, and seemed to be lighted from beneath. Refreshed I got up from the water and into a room that was connected to the cave. I guess there were plenty of rooms like the one I got into, and they were all connected to their private caves. The caves themselves were connected by water.

Suddenly I notice something is coming up from the water, into the room. I turn around to see what it is. It's a swan. A beautiful, large, white swan. We watch each other for a while. Then I drive it into the water and I guess it swims away.

Another dream followed and it was beautiful. I woke up very happy.
