You walk into a room and suddenly your brain goes fuzzy with an overwhelming wave of familiarity -- although this is a totally new experience. Like something out of a sci-fi plot, it almost seems as if you've walked into the future.
Chances are, you've experienced this situation, known as déjà vu, during your life. Déjà vu (French for 'already seen') occurs in approximately 60 to 80 percent of people -- a phenomenon that's almost always fleeting and may manifest at any time. Despite wide-spread coverage, bursts of déjà vu are still misunderstood by the scientific community.
