The main idea of this video is imagination. A boy saves a fish and imagines that it becomes a mermaid. He then gets arrested because the world he lives in does not allow imagination. During his time in prison, it seemed like the government were torturing him, trying to make him forget about the mermaid. Times passes, and the boy starts to forget what the mermaid looked like. Then, he escapes and goes back to where he found the fish in the first place. At the end, the mermaid shows up again and the boy also goes into the ocean and they both disappear. I think this video is trying to tell us about how society control our thoughts and how education took away children’s individuality.
