I was taken from the ocean,
Cast far away.
It's time to run,
I should be set free.
Please let me go, or you'll be sorry.
Who am I?
To address the question being closed for being too broad, there is a distinct answer that fits all statements when solved. Every line except the first and last contain a direct literal reference to the answer. Next time I will be more clear that the answer should fit literally within the context of words in the inner three lines which will address the concern of over-generality.
Not familiar with the grounds for re-opening so probably won't push for that, will add this edit here for anyone still interested in solving, and will edit the answer in, in a week.
I can release the first clue too which makes the solution more obvious:
All references should be forgotten.
