The term déjà vu is French and means, literally, “already seen.” Those who have experienced the feeling describe it as an overwhelming sense of familiarity with something that shouldn’t be familiar at all. Scientific approaches reject the explanation of déjà vu as “precognition” or “prophecy“, but rather explain it as an anomaly of memory, which creates a distinct impression that an experience is “being recalled”

Reminder

You’re remembering something else. An object, a smell, or a sound has triggered a memory you’ve already stored. That’s creating a sense of familiarity even though you’re having a new experience.

Short circuited

Your brain just short-circuited. Something went wrong, and the sensory input you received has loaded up an unrelated memory accidentally. In other words, your mind is literally playing tricks on you.

Organized thought

You are recognizing a pattern. The human mind has an amazing capacity to spot and remember patterns. The way the furniture is designed, the way the garden grows, even a familiar pattern of speech can trigger a sense of déjà vu as a result.

Too much input

Your brain just overloaded. When you see something for the first time, it activates a specific area of the temporal lobe. When you are seeing something familiar, another part of the temporal lobe becomes active. Both these parts of the brain send information to the hippocampus. When they’re both transmitting signals, your brain may become overloaded. This creates confusion, and suddenly a familiar feeling is assigned to a new object.

Epilepsy

You’ve got epilepsy. The feeling of déjà vu can occur just before you have a seizure in the temporal lobe of your brain.

Misfile

Your brain just put something in the wrong file. It’s like when you accidentally save a picture in your documents folder. You’ve got déjà vu because your brain just accidentally misfiled the information it was trying to store. You just saw something new so it should immediately become part of your short-term memory, but your brain made a mistake and put it into the long-term memory folder instead. This creates that odd feeling of the familiar.

Anxiety

You are way too anxious. In studying a British man who had feelings of constant déjà vu, scientists have formulated a relatively new theory about this phenomenon. The subject in this particular case felt that everything was familiar, even TV shows and news stories. Scientists believe these feelings may be caused by extreme anxiety.

Miscommunication

miscomm

Your hemispheres are miscommunicating. The two halves of your brain are like any other couple: sometimes, they have trouble communicating. Some theorize that as your brain transmits information from one side of the brain to the other, there is a delay. That sense of déjà vu may come when one half of your brain gets the same information twice, once from direct stimulus and then again from the other half of the brain.

False Memory

You’ve got schizophrenia. People who have schizophrenia experience what’s known as false memories, feelings or impressions that they’ve done something they have, in fact, never done before. This feeling is similar to, and often confused with, déjà vu.

Divided Attention

Your attention span isn’t so hot. In trying to recreate déjà vu, scientists have developed the “cellphone” theory, also known as divided attention. What’s happening is this: your brain is subconsciously collecting information, so quickly that your conscious mind is not aware of it because your mind is somewhere else. When you focus on your surroundings a moment later with full attention, you feel as though you’re seeming something you have already seen — because you are.
