If you've heard the phrase "my life flashed before my eyes", it's pretty self-explanatory what life review means.

For over a century, life reviews were well reported but there aren't much studies about it. There are two theories as to why this happens:

• The first theory is that life events may exist as a continuum in our minds, and may come to the forefront in extreme conditions of psychological and physiological stress;
• The second is that our memories "unload" themselves when we're on the brink of death like cortical disinhibition, but usually serene and ordered, not chaotic.
