![]() ![]() Cleary said she believes this might happen when you dream about something you’ve experienced, but later only remember the dream, not the event itself. There’s actually a term for dream déjà vu: déjà reve, French for “dreamed before.” About 86% of college students surveyed as part of a study report reliving events they remember from dreams. Add that to the already fallible memory system of our brains, and you can see why the two might interact to create a feeling of familiarity maybe you dreamed it, or something like it. Dreams are notorious for being less than faithful to reality. Perhaps when we’re tired, stressed or distracted we only recall a fraction of an event, just enough to trigger a sense of familiarity.Ī 2010 study found those of us who frequently remember our dreams seem to have more déjà vu experiences. Research also shows déjà vu is more likely to happen if a person is under pressure or fatigued. These types of memories might be what drive the sense of familiarity that presumably underlies déjà vu.” “However, just because something fails to be recalled doesn’t mean that the memory isn’t still ‘in there’ somewhere often it is, and it is just failing to be accessed. We simply fail to recall everything that we encounter in day-to-day life,” explained déjà vu researcher Anne Cleary. If déjà vu is all about familiarity-based recognition, there’s some logic to these statistics: Travel is most common among those with higher incomes, and traveling provides more opportunities to see new physical locations that might trigger a sense of familiarity, especially if those locations may have appeared in a previously viewed movie scene. We now know the brain isn’t fully formed until at least age 25, maybe even later.ĭéjà vu is also most common in people with higher education and socioeconomic class, and those who watch more movies and travel often. Déjà vu episodes drop dramatically in older adults in fact, most reports come from people between age 15 and 25, leading some to wonder if déjà vu is connected to brain development. While there’s no gender difference when it comes to the phenomenon, age does seem to matter. Most researchers who study this area of the brain vote for the last option, and they are busy trying to find all the reasons why.Ībout two-thirds of us experience déjà vu at least once in our lives, experts say. Is déjà vu evidence of a past life, an out of body experience or just a good old neural misfire? The phrase déjà vu is French, meaning “already seen.”īut we know less about why we have the feeling. Déjà vu is the belief you’ve been here or done that before, when you know there’s absolutely no way you could have. We know the feeling (or at least 66% of us do). ![]()
