Okay in this section I want to talk about 'deja vu'. Have you ever heard about deja vu? based on https://science.howstuffworks.com the term déjà vu is French and means, literally, "already seen". So deja vu is one condition that you have already seen before, for example, when you have a dream to buy a red car with type xxx in the past, but in this present time you really buy that car with the same type and color or maybe you are having dinner with a group of friends, discussing some current political topic, and you have the feeling that you've already experienced this very thing same friends, same dinner, same topic. This phenomenon is very strange, I don't know why maybe this has to do with our sixth sense. Those who have experienced the feeling describe it as an overwhelming sense of familiarity with something that shouldn't be familiar at all. Since déjà vu occurs in individuals with and without a medical condition, there is much speculation as to how and why this phenomenon happens. Several psychoanalysts attribute déjà vu to simple fantasy or wish fulfillment, while some psychiatrists ascribe it to mismatching in the brain that causes the brain to mistake the present for the past. Many parapsychologists believe it is related to a past-life experience. Obviously, there is more investigation to be done.
