Are You Surprised To Experience A New Event As Seen? Learn About Reasons For Deja Vu

Each of us had an experience when we see something for the first time and feel as if we have already seen this before. This phenomenon is called deja vu, which in French literally means “already seen.” In folk psychology, this erroneous familiarity of what we see for the first time is interpreted as precognition or prophecy of future events; or we explain this phenomenon by connecting it to our forgotten dreams. Here are more explanations of deja vu.   

1.Mistake in the Brain

When you are seeing something new and feeling that you have already experienced this scene, it is quite possible that your own brain pokes fun at you. A sensory input accidentally overloaded your memory and messed it up. In short, as it happens with computers, something went wrong when information from the outside world entered your brain.


When you see a new scene, you are recollecting something else in addition to it. A new sound or smell, or view brought out a forgotten event from the deepest recesses of your memory. The overlapping of the old memory and the new scene creates an illusion of deja vu. Yet, in reality the two events are connected only by association.

3.Schemata And Scenarios

Our brain remembers information by slotting it according to schemata and scenarios it keeps inside itself. These schemata are created in our brain, after we have an experience of some event. We would not be able to function without them. For example, we have a restaurant schema in our memory, which helps us behave as we are expected to behave in a restaurant and not to get surprised every time when a waiter approaches our table. When we have a deja vu experience, our brain recollects the schema of the event we are experiencing rather than a particular event.

4.Danger Signal

If you suffer from epilepsy, the experience of deja vu might be a signal that a seizure is coming. It is a center of epileptic activity is being activated in the temporal lobe of your brain.

5.Excessive Information From The Outside

It well may be that, when you are having a sense of deja vu, your brain might be overloaded. When you are encountering a new event, one part gets activated in the temporal lobe of your brain. When you encounter something you have already seen before, another part is activated there. Both these parts of the brain send signals to hippocampus. If both parts of the temporal lobe send signals simultaneously, your brain might get confused and might ascribe the feeling of familiarity to a new object.

6.High Level Of Anxiety

Some scientists aver that the feeling of deja vu is triggered by excessive anxiety. They observed a patient who constantly had a feeling of deja vu. He experienced as already seen even new TV programs and shows. In addition, this patient was highly anxious in general, which led doctors to hypothesize that the deja vu phenomenon might be connected to anxiety.

7.Communicative Problems

Our brain has the left and right hemispheres and constantly transmits information from one hemisphere to another. Sometimes, this information is not passed accurately. Some scientists say that when one hemisphere transmits information to another hemisphere, occurs a delay. The experience of deja vu happens, when one part of your brain receives the same information twice: once directly from the stimulus and then again from another part of your brain.
