What is Déjà vu? What does science say about this memory illusion?
Déjà vu: what is it?
The French word déjà vu, which means "already seen," describes the experience of having the impression that an event has already happened. When time travel is connected, déjà vu phenomena can be observed. It separates into two distinct halves, one of which is different from the other, and occasionally humans may feel the difference between these two lines. Because of this, a person may recall an occasion or location more than once; this is known as déjà vu. When experiencing deja vu, a person believes that the current circumstances have already happened to him in the past. Some individuals think that this occurs when someone alters the past by travelling into the future.
the scientific basis behind déjà vu
If we discuss the scientific justifications behind it, then researchers claim that our brain is divided into two sections, one of which controls our right side body and the other our left side body. One half of our brains may believe that this has occurred to me before while we are experiencing mental fatigue or a hangover since the signal does not reach both sides of our brains at the same time, even after a brief delay.
