The term déjà vu is a French term coined by a French psychic researcher named Émile Boirac. Déjà vu means “already seen,” and is also called “paramnesia.” It describes the feeling of having already experienced a situation. When experiencing déjà vu, one is struck with feelings of familiarity and strangeness, which can make one feel that the situation has truly happened before.
Approximately two thirds of adults claim to have had a déjà vu experience. Déjà vu experiences have been connected with medical conditions, such as schizophrenia, epilepsy, and anxiety. No one really knows what causes these episodes, although psychologists have also come up with theories such as stress and internal hidden conflicts. Some believe déjà vu is the memory of previously forgotten dreams. Still others associate it with psychic abilities, prophecy, or past-life experiences.
A déjà vu experience could be the result of God revealing certain things to a person before the event occurred, but the experience could also simply be the result of something occurring that is very similar to an event in the past. The event triggers the memory, causing an "eerie" sense of familiarity. Rather than being a spiritual issue, déjà vu is likely a simple and harmless physical one.
