The references given in a comment (in thefreedictionary and urbandictionary) suggest the meaning, "to feel unhappy or strange because you are in a situation that you are not familiar with", but provide no sense of why it should mean that. It is a reference to classical elements, Earth, Water, Air, and Fire; as, for example, a fish out of water is out of its element.
