Déj vu

Have you ever experienced déj vu (French for 'already seen') - the feeling that something has happened before, when in fact it is happening for the first time? Déj vu is more common in younger people, in people with a certain form of epilepsy, and also when you are ill, tired or stressed. It may last for just a few seconds or several minutes. How your mind can fool you in this way is still a mystery although there are several theories about it.

Déj  vu can be a confusing experience.
