Sheepdog in a Fishtank

Date: 4/19/2020

I dreamed about a very large fishtank filled with water and lots of small blue fish. There was a sheepdog resting at the bottom of the fishtank (yes, underwater). He was looking up at all of the fish and watching them. Then all of a sudden he decided he wanted to leave. I watched this in shock and immediately wanted to rescue the dog. But by the time I got closer to the fishtank the dog jumped out of it, and onto a very high-up platform.
