![]() Ultimately, déjà vu is further proof that the human brain is amazing. "Déjà vu is actually a good sign, and seems to reflect the brain's ability to process memories at different levels and at differing speeds," says Giordano. ![]() "Some propose that this is why déjà vu has that eerie feeling of semi-remembering, or feeling like you’ve been there before but can’t seem to put your finger on it." Because, let's be honest, who hasn't felt a sense of eeriness when it comes to déjà vu? "It might be possible that déjà vu occurs when you detect familiarity, stimulating the rhinal cortices, but don’t activate the hippocampus, which helps you recall more concrete memory details," says Winters. tells Bustle.īut, like Giordano, Winters agrees that it does come down to how the brain processes memory and the occasional mismatch, making it a cross between a memory error and a "neurological impulse glitch." You may also be more familiar with the situation that sparks déjà vu than you think. "Some propose that this is why déjà vu has that eerie feeling of semi-remembering, or feeling like you’ve been there before but can’t seem to put your finger on it." Because, let's be honest, who hasn't felt a sense of eeriness when it comes to déjà vu?"Because déjà vu often occurs suddenly - with no warning - and is fleeting in duration, it’s incredibly hard to study in a clinical setting in a healthy population," neuroscientist & holistic wellness expert Leigh Winters, M.A. "Because déjà vu often occurs suddenly - with no warning - and is fleeting in duration, it’s incredibly hard to study in a clinical setting in a healthy population," neuroscientist & holistic wellness expert Leigh Winters, M.A. Here are seven reasons why you experience déjà vu, according to experts. networks of the hippocampus and temporal lobe that function in memory and areas of the limbic system and prefrontal cortex that function in decision-making." Coordinating these networks can be complicated, and sometimes they don't sync properly - and you feel as if you've had this exact conversation or experience before, even if it's totally new. "These processes involve a number of brain networks, including regions of the sensory cortex that function in sight, hearing, touch, smell, etc. ![]() "Déjà vu occurs because the brain uses both a 'fast' process of immediate sensation and memory, and a 'slower' process to integrate past memories and present experiences," James Giordano Ph.D., professor of neurology at Georgetown University Medical Center, tells Bustle. It can feel like your mind is playing tricks on you - but of course, when it comes to all things related to the brain and brain function, it's far more complicated than that. In French, déjà vu literally means "already seen," even if you haven't already seen what you're seeing. It can be a dreamlike, surreal feeling, especially if you know you've never been to that place in your life - and it's incredibly common.
