Deja vu is a French word meaning "already seen", it has also been described as a feeling or experience that one
has seen or done something before. For example, you are waiting in line to check out at the grocery store and the
lady behind you asks you to hand her a pack of gum. Suddenly you get an overwhelming feeling that you have
been there in that exact same spot, talking to the same lady, even the same brand of gum. Even though everything
seems so familiar you know there is no way that could have happened before. There are many theories as to why
and how this phenomenon happens. One theory is that deja vu is connected with temporal-lobe epilepsy, but
people without a history of epilepsy have also experienced deja vu. Psychiatrists believe it is something in your
brain that confuses an event that happened in the past with the present. Another theory is parapsychologist think it
is connected with past life experiences. Whether deja vu is an experience of the paranormal or simply some
confusion in the brain, it is a perplexing feeling of having "already seen."
