What is Deja Vu?
According to Wikipedia, Deja Vu is the feeling that the situation currently being experienced has already been experienced in the past. (Wikipedia)
The phrase “Deja Vu,” is French and means “already seen.” (Wikipedia) People who have experienced it, say it is an overwhelming sense of familiarity with something that really shouldn’t feel familiar. I think most of us have experienced this phenomena. For example, if you walk into a new coffee shop and even though you have never been there before you feel like you have or may have some kind of memory similar to that particular one.

As much as 70 percent of the population reports having experienced some form of deja vu. A higher number of incidents occurs in people 15 to 25 years old than in any other age group. – How Stuff Work
There are many theories as to what Deja Vu actually is. It is a pretty complex topic. Deja Vu has been heavily associated with temporal-lobe epilepsy. Many have reported experiencing Deja Vu before a temporal-lobe seizure. People who suffer from this kind of seizure can experience Deja Vu before the seizure, in between convulsions, and even during the convulsions. There is a lot of questions as to why this happens because people with and without medical conditions have experienced it.
Many psychoanalysts believe Deja Vu could be caused by a simple fantasy or wish fulfillment. Some psychiatrists say it is a mistake in the brain, making it confuse the present for the past. Several parapsychologists actually believe Deja Vu could be related to a past life experience. (How Stuff Works)
In 2004 there was a review done that showed that about 2/3 of the population has had Deja Vu experiences. Some studies have confirmed that experiencing Deja Vu is healthy. Although, experiences of Deja Vu that are prolonged and associated with other things like hallucination, could mean that the person has some kind of neurological or psychiatric illness.
“Deja Vu doesn’t help predict the future, with researchers in 2018 concluding that over half the time that these experiences are just feelings and were no more accurate at predicting the future than random chance.” – Wikipedia
There are actually certain medications that can increase the chances of someone experiencing Deja Vu. In 2001, there was a case where a healthy man started experiencing intense and reoccuring sensations of what they believed to be Deja Vu. These medications were amantadine and phenylpropanolamine. They were prescribed to treat the flu. The man was so interested by this that he kept taking the medications and recorded all of the things he experienced so he could report them to psychologists. This was so they could do a case study. (Wikipedia)
I think Deja Vu is something that we have all experienced in our lifetime. Whether it’s some supernatural gift or just a fluke in the brain, I’ll let you decide. Either way, I think it is a pretty interesting topic. I hope more research is conducted on it in the future.
