Déjà vu is the sense of having seen something before, and a feeling of familiarity whereas déjà vécu is the experience of having seen an event before, but in great detail such as distinguishing smells and sounds. This is also typically go with by a very strong feeling of knowing what is going to come next.
In my own experience of this, I have not only known what was going to come next, but have been able to tell those around me what is going to come next. This is a very creepy and unexplainable feeling. It is the phenomenon of having the strong sensation that an event or experience currently being experienced has already been experienced in the past.
Scientific approaches reject the explanation of déjà vu as “precognition” or “prophecy”, but rather clarify it as an anomaly of memory, which creates a different impression that an experience is “being recalled”.
This clarification is supported by the fact that the sense of “recollection” at the time is strong in most cases, but that the situations of the “previous” experience (when, where, and how the earlier experience occurred) are uncertain or believed to be impossible.
Two main types of déjà vu are suggested to exist: the pathological type of déjà vu usually associated with epilepsy and the non-pathological which is a characteristic of healthy people and psychological phenomena.
A 2004 survey concluded that approximately two-thirds of the population has had déjà vu experiences. 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 extended or frequent, or in connection with other types of symptoms for example, hallucinations, may be an sign of neurological or psychiatric illness.
