Vae faces the sea. What do you mean I became the sea?

"Facing the sea, I stood in the sea." Times have changed, and now I am the sea.

Analyzing the lyrics of "The Art of Photography", "Facing the sea, I stand in the sea, and you float and sink in my room", seems inexplicable, but it is actually a mystery. The sea actually refers to a wide range, but from the following "memory is a mad dog", we can guess that the sea here is related to memory. So we can boldly speculate that the sea means "you". On this basis, we continue to analyze.

Facing the sea, I stood in the sea. At that time, "you" was as awesome as the sea, but times have changed. Now that I am the sea, you can only float and sink in me.
