Déjà vu is real
Déjà vu has a supernatural reputation. But the feeling of having already experienced a situation of the present while it is occurring occurs when the brain sends signals to see if there was any type of “memory error”. In other words, the phenomenon is our brain checking if there was any inconsistency between what we really live and what we think we live. Have déjà-vu can be a good sign because it shows that the “memory check” system is working well and you are less likely to confuse past situations with present ones.
