The term déjà vu is French and it means “already seen.”. There are also two other kinds of déjà vu: déjà entendu which means, “already heard” and déjà vecu which means, “already lived.”. Many people experience déjà vu, but they don’t understand what’s going on. We’ve all been in a situation where we felt that we’ve seen exactly what’s going on, happening before.
70 percent of the population reported that they had experienced some form of déjà vu, and a higher number of incidents occurs in people aged 15 to 25 years old. Overall, the amount of times someone experiences déjà vu decreases after the age of 25. Déjà vu could be directly correlated with dopamine levels in the brain, and this explains why younger people may experience déjà vu more often.
Déjà vu happens really randomly and quickly, thus it’s hard to study and understand. Yet scientists and researchers are doing their best to understand it. During Sigmund Freud studies of déjà vu, he believed the feeling had to do with the memory of an unconscious dream. Parapsychologists believe that déjà vu has more to do with a person’s past life, meaning when you experience déjà vu, it is the memory of your former self.
