Dejavu is when you feel in your mind and body you have been in a place, situation or encounter before, but you know you haven't.
The reason that dejavu happens is that your brain is always giving you options before any situation. Sometimes it will give you 1 or many scenarios. If it happens in real life that one of the scenarios was thought ahead in your brain it seems like you have been in that situatio. Undersand? Usually the younger you are the more active your brain is and you might experience more dejavus. any more Q. let me know
