Have you ever visited a place, and then you felt that this place was frighteningly familiar to you?
Or  maybe during a deep conversation with a friend of yours, you   suddenly  felt that you had orchestrated this conversation before?   Although you did not do it!
If you find yourself in any of these situations, you have already experienced the deja vu (they already saw)

About  60-70% of people have experienced this feeling at least once in   their  lives. To see something, to hear a voice, to taste a taste, or  to  smell a  certain scent may make us feel that we have passed it  before,  That has never happened

The  Dutch psychologist Hermon Sno suggested that memories resemble  stereoscopic images, which means that you can recreate a  three-dimensional image from any part of the whole, even a smaller part  of some memories, and finally give you a final hazy image. The  deja vu occurs due to the presence of some details in the environment  in which we are currently present (scene, sound, smell, etc.),  resembling some remnants of memory in the past, and our brain forms a  whole scene of that piece of memories
