Déjà Vu

       Déjà Vu is French meaning already seen. This phenomenon of having the strong sensation that an event or experience currently being experienced has been experienced in the past, whether it has actually happened or not. Scientist explain it as an anomaly of memory, which creates a distinct impression that an experience is "being recalled". One theory is the events are stored into memory before the conscious part of the brain even receives the information and processes it. However, this explanation has been criticized that the brain would not be able to store information without a sensory input first. Other studies confirm that déjà vu is a common experience in healthy individuals, with between 31% and 96% of individuals reporting it. Déjà vu experiences that are unusually prolonged or frequent, or in association with other symptoms such as hallucinations, may be an indicator of neurological or psychiatric illness.
