In this picture I don't see as much mist, neither do I see any books. So I can't see this as being the dream of a student. Despite that lizard on the very bottom right corner of the picture, I see that the girl is in a place free of distraction; there aren't any animals around that could attack, neither are there any people around. The glass capsule is extremely large and in the form of something that would be used to contain a type of medicine. The tiger in the boat doesn't look malicious towards people, neither does it look scared. The water isn't gushing out of anything. And here again the girl is in the attitude of trying to figure something out.
I could see this being the dream of a doctor who is on the verge of finding a medicine that could cure a well known disease or ailment. He/she is so anxious to extract that life saving component that could successfully attack that life-taking pathogen. That component is very close and within reach. But the frustration lies in figuring out what more needs to be done to extract it from a certain solution. This doctor has everything that he needs in his laboratory, but it's just trying to figure out how to isolate it. I may comment more on this picture again later to do another interpretation.
But surely the girl is there in the attitude of wonder as to how she is going to release something powerful that can save life.
The color scheme is dark, but it's not evil or hopeless. But instead it is serious, somber, and in the mood for deep thinking or figuring something out.
I love this picture because it inspires thought, creativity, and deep thinking. Truly this picture has depth and complexity to it. You did a very nice job! Thank You For Posting it!
