I'll write about the video mirage.
In the video, the main character is a robot like a boy. He has water in his stomach and the water is decreasing as he walks. So, he can't live without water. He climbs a ladder to get water which is on the top of the ladder. However, when he reaches the top and he starts walking, he falls down and the water spills. He feels shock. Then, he finds the shining ball in front of him. He tries to poke it and the water comes out of it. His stomach is filled with the water. But, there was a goldfish in the ball, so it can't live because there is no water in the ball. That's why he put it into his stomach, and finally he lives with a goldfish.
I think the theme of this video is we should be able to stand on our own feet. If we face with any emergencies, we have to live for ourselves.
