The confusion and mystery surrounding this feeling only make it more skin-crawling. Carl Jung has referred to it as something "immemorially known." Some people speculate that deja vu has to do with past lives or alien abduction. Some researchers have said that deja vu is a way for your brain to know your memory checking system is working well. Doctors and psychologists don't seem to have a straight answer either. Déjà vu is the sensation that a place or event someone is currently experiencing has been experienced before, even when that cannot actually be the case. Some people insist that it's some sort of glitch in the matrix, while others think it's a sign of a mental illness. There are lots of theories about the phenomenon. The moment is so fast and comes out of nowhere, so it's really difficult for scientists to study and research. It was originally developed by Dutch scientist Herman Sno who did extensive research on deja vu. Those hair-raising stories are often hard to explain, mainly because deja vu itself is hard to explain. This is an interesting example of the science behind deja vu and is based on the so-called hologram theory which argues that the perception and memories are like holograms. The only thing weirder than feeling deja vu is reading some of the creepiest instances of deja vu that pop up on the internet from time to time. The official definition of the phenomenon, according to Merriam-Webster, is, "a feeling of having already experienced the present situation." The feeling is fleeting, often comes up out of nowhere, and can leave you a bit unsettled.

That's because, to put it simply, deja vu is creepy. Chances are good that, at some point in your life, you have experienced some form of deja vu - and chances are also good that that experience was probably a little bit strange.
