What causes it?
Ø Most scientists agree that déjà vu has to do with memory. Psychologists that study memory point out that we have memories for things that happened to us, and also memory for where those things happened to us. The memory for where we encountered information is called source memory.
Ø Some people believe that déjà vu involves emotional responses to similar events and others think that the brain short circuits and sends events to our memory a split second before putting it into our consciousness.
Ø Another look into causes of déjà vu comes from studies of epilepsy. There is a link between déjà vu and seizures that occur in people with temporal lobe epilepsy. It is a type of epilepsy that affects the brain's hippo-campus.
Ø This has led some experts to suggest that déjà vu, like an epileptic seizure, could be caused by neural misfiring, during which neurons in the brain send signals at random.
Ø Research suggests that déjà vu is caused by miscommunication to the brain.
Ø Some theorists go as far as to say that déjà vu happens when parallel universes temporarily sync, and that it’s an indication that the same thing is happening somewhere else.
Ø People say that your subconscious mind can see your future while you dream and that translates into déjà vu when you are awake.
Ø The more tired or stressed out you are, the more likely you are to experience déjà vu.
Ø People say that déjà vu is the brain’s way of telling you that you are in the right place at the right time.
