Have you ever feel Déjà vu or Jamais vu?? Know About this uncanny sense.

Déjà vu

Déjà vu(already seen) is a French loanword expressing when a person has done something and they experience the same feelings or the feeling that one has lived through the present situation before. 

It is an anomaly of memory whereby, despite the strong sense of recollection, the time, place, and practical context of the "previous" experience are uncertain or believed to be impossible. 

Two types of déjà vu are recognized: the pathological déjà vu usually associated with epilepsy or that which, when unusually prolonged or frequent, or associated with other symptoms such as hallucinations, may be an indicator of neurological or psychiatric illness.

People who travel often or frequently watch films are more likely to experience déjà vu than others.

Research has associated déjà vu experiences with good memory functions. Recognition memory enables people to realize the event or activity that they are experiencing has happened before.

When people experience déjà vu, they may have their recognition memory triggered by certain situations which they have never encountered.

⭐Jamais vu:

Jamais vu (never seen) is any familiar situation which is not recognized by the observer. jamais vu involves a sense of eeriness and the observer's impression of seeing the situation for the first time despite rationally knowing that they have been in the situation before. 

Jamais vu is more commonly explained as when a person momentarily does not recognize a word, person or place that they already know. Jamais vu is sometimes associated with certain types of aphasia.

Theoretically, a jamais vu feeling in a sufferer of a delirious disorder or intoxication could result in a delirious explanation of it, such as in the Capgras delusion, in which the patient takes a known person for a false double or impostor.

The feeling has been evoked through semantic satiation. Sixty-eight percent of the subjects reported symptoms of jamais vu, with some beginning to doubt that "door" was a real word.

The experience has also been named "vuja de" and "véjà du".
