Black snake with green eyes in a fountain

I am in a large open room like a museum or art gallery. The only thing in the room is a large fancy fountain like you see in parks. In the fountain coiled up in the center island is a large black snake. At first I am afraid when I see it but then it looks at me and I feel calm. The snake has brilliant emerald green eyes. I feel like it is trying to tell me something but then I wake up. This is a recurring dream I have. In my personal life there is no pattern I can determine. Sometimes I am having difficulties and a lot of stress, sometimes life seems pretty calm.
