Many of us have experienced déjà vu - the unsettling sensation of knowing that a situation could not have been experienced, combined with the feeling that it has. It is usually so fleeting that psychologists have until recently thought it impossible to study. But for some people, the feeling of having been there before is a persistent sensation, making every day a ‘Groundhog Day’.

I have some kind of belief that all of life has happened before and we're just reliving it. ...What is this feeling or phenomena?
Eternal return (also known as "eternal recurrence") is a concept which posits that the universe has been recurring, and will continue to recur in a self-similar form an infinite number of times. The concept has roots in ancient Egypt, and was subsequently taken up by the Pythagoreans and Stoics. In the Hebrew Scriptures, the notion is supported in the book of Ecclesiastes. With the decline of antiquity and the spread of Christianity, the concept fell into disuse, though Friedrich Nietzsche briefly resurrected it.
