What is Deja Vu? 

Déjà vu is the feeling that one has lived through the present situation before. It describes the unusual occurrence of an incident feeling much more intimate than it should. 


It describes the fascinating and peculiar experience where you feel that something is extremely familiar. Still, at the same time, you know somewhere deep inside that this feeling of supreme familiarity should not be as powerful as it is.

Dr. Akira O’Connor, a senior psychology lecturer at the University of St Andrews, says, “Déjà vu is basically a conflict between the sensation of familiarity and the awareness that the familiarity is incorrect. And it’s the awareness that you’re being tricked that makes déjà vu so unique compared to other memory events.” 

What causes Deja Vu?

Deja Vu is not something that can be studied easily by researchers as it occurs without any warning. 

Deja Vu lasts for a few seconds and ends even before entirely realizing what just happened. It gets almost impossible to track Deja Vu’s causes, but after years of research, Deja Vu’s occurrence is a few possibilities. 

Split Perception

According to the split perception, déjà vu occurs when a person views the same thing at two different times.

The first time a person sees something, it goes unnoticed to the brain as only a corner of the eye views it, and he/she is distracted while seeing it. 

This happens without the person’s notice, the brain starts forming a memory of what the person has seen with the limited amount of information the eye has captured the first time it has seen something. 


This way, the brain forms a memory of the incident without creating a memory in their conscious mind. 

Now, when the person sees the same thing, the person is immersed in the experience, unlike the last time when it went unnoticed. 

But as the previous perception is a memory in the brain now, the brain recalls it, and you tend to be aware of what is happening or what is going to happen in the next few minutes, making you experience Deja Vu. 

Malfunctioning of the Minor Brain

After years of research, numerous studies suggest that Deja Vu happens when a person’s brain glitches or dysfunctions for a few seconds. 

There are instances where the brain mixes up events, the timeline of incidents, and gets confused. It then recalls memories from the past into the present event and when the past memory dominates what the person is currently experiencing, Deja Vu occurs. 

In short, the brain is wrongly distinguishing the present and the past, causing a Deja Vu. 

Disorientation of the Memory path 

Similar to the malfunctioning of the minor brain, some studies have shown that there is another way in which the brain malfunctions which results in causing Deja Vu. 

When the brain absorbs some information, a specific path is followed for the brain’s information, from short-term memory storage to long-term memory storage. 

Sometimes, this information tends to bypass the short-term memory and enter the long-term memory. 

So when a person experiences deja-vu, it is the brain retrieving a false long-term memory. 

Delayed Processing

Many scientists support the theory that when a person observes something, the information is processed by the senses and then transmitted to the brain in separate routes.

One of the routes is known to be faster than the other, but the delay is exceptionally insignificant.

Sometimes, the delay increases by a fraction of a second, making the person perceive the same event as two separate incidents. 

Some interesting Deja Vu facts

Deja Vu is highly connected to the psychology of a person. 

For those who don’t know what psychology is, it is a vast topic that deals with how a person’s brain behaves in various instances. 

Below are some unknown and interesting Deja Vu facts.

Attention 


There are high chances for the occurrence of Deja Vu when the person is not paying attention. A distracted person is more likely to experience Deja Vu. 

This distraction can be related to the split perception theory, where a person’s perception can be split into two different perceptions, making him/her confused. 

The millisecond distraction causes split perceptions which in turn causes Deja Vu. 

Dominant Eye 


According to Dr. Michael Roizen and Dr. Mehmet Oz, both eyes being equal is a myth, and every person has a dominant eye. This is one of the highly interesting Deja Vu facts.


When the dominant/stronger eye sends information to the brain subconsciously before both the eyes focus and register the event and transfer the incident to the brain.

There is a millisecond delay in the dominant eye sending the information subconsciously and when the eyes send it to the subconscious brain, it is the second time the incident is occurring according to the brain. 

Stress

Stress, excessive traveling, exhaustion, and irregular sleep schedules cause Deja Vu. Though the exact reason why this causes Deja Vu is unknown, it is possible that a person has the urge to shut his /her eyes when under stress which causes malfunctioning of the brain. 

Turning Fork phenomenon 

People who believe in the existence of more than one universe put forward this phenomenon. 

This phenomenon says that when frequencies of a person’s mind temporarily match the frequencies of other living people’s minds or subtle bodies in the afterlife, Deja vu occurs. 

Bad Memory 


Sometimes, Deja- Vu is just due to a person’s bad memory. The person has faced the same situation in the past but just does not remember the whole incident. 

It is most common in travelers as they travel a lot, and while traveling, they come across several new places for very short periods of time that their brain cannot remember everything. 

Now that you know what Deja Vu is and what causes it, let us discuss some of the ways in which you can avoid it.

How can you prevent Deja Vu?

Now that you know several Deja Vu facts, let us see how Deja Vu can be prevented.

Deja-Vu, if occurring numerous times, is serious and can start impacting a human’s brain.

There have been instances where a person who experiences Deja Vu regularly cannot differentiate between reality, present, past, and dreams. This will affect the everyday lifestyle of a person. 

Here are some tips which you must follow to avoid or prevent Deja Vu. 

Remove the feeling 

Every time you sense Deja Vu, instead of thinking about it and stressing your brain about it, distract yourself by doing something else immediately. 

Focus 

When the Deja-Vu you are facing is severe, you might lose focus. It is essential to start focussing, and the best way to do that is to count 10 to 1 backwards. 

Breathe 

Taking deep breaths will supply oxygen to your brain and help you relax and help the brain get rid of the Deja Vu feeling.

Avoid Drugs 

Certain drugs and other illegal substances mess up a human’s brain and take the brain to places filled with imagination, causing several Deja Vu’s when not on drugs. 

Taking drugs, in the long run, will have a severe impact on the brain, and the brain will be unable to process reality.

Rub your hands 

Rubbing hands intensely when facing Deja Vu will divert your focus to the heat generated between your hands and will quickly change the brain’s attention. 

Understand Deja Vu 

Do not panic when you are experiencing Deja Vu. Understand that Deja Vu is a common phenomenon faced by almost everyone, and it is not something to be worried about.

Stop stressing yourself about Deja Vu, as worrying will just make it worse.
