HI! Could you tell me please how to explain the following sentence: "I am I was I am to come my was"

It is not correct grammar, and has no clear meaning.

It sounds perhaps like an attempt at very cryptic poetry.

Sorry. It's just an odd collection of words with no coherent meaning. Emotion: sad

I think it comes from poetic.

If you were to ask me, I would say that it means I am who I am. It does not matter who I am today or who I was in the past. What really matter is that I am about to become "the old me."
Students: Are you brave enough to let our tutors analyse your pronunciation?
Some time ago I was asked to explain it and,of course, I had no idea what it meant. But I was told that it's possible to be translated...That's why I'm asking. Thanks for help!
