Actually, What Is Dejavu and Why Can It Happen?

Dejavu is a situation where you feel familiar with the conditions around you, as if you have experienced it in exactly the same situation, even though what you are experiencing now is probably your first experience. This event can last 10 to 30 seconds, and more than once. If this happens to you, you don't need to panic, because according to some studies, two to three people who have experienced dejavu will experience it again.

Dejavu aka "déjà vu" comes from French which means "I've seen". This title was first coined by Émile Boirac, a philosophical and scientist from France in 1876. Many philosophers and other scientists tried to explain why dejavu could occur. According to Sigmund Freud, the occurrence of dejavu is related to pent-up desires. While according to Carl Jung, dejavu is related to our subconscious.

The exact explanation regarding the reason for déjà vu is difficult to find because the study of dejavu itself is not easy to do. Researchers can only hold on to someone's retrospective dejavu experience, making it difficult to find a stimulus that triggers a dejavu.

But there are some theories that might answer why you experience dejavu:

Dejavu because of temporal lobe seizure

The cause of temporal lobe seizure, aka temporal lobe seizures, is sometimes unknown. But trauma to the brain, infections, strokes, brain tumors, and genetic factors can cause temporal lobe seizures. When experiencing an attack, a temporal lobe seizure sufferer can experience a decreased ability to respond to the surrounding environment to perform the same activities over and over again, such as clicking the tongue or moving the fingers unnaturally. Before this attack comes, usually the temporal lobe seizure sufferers will experience strange sensations such as feeling unreasonable fear, hallucinations, and dejavu.

Dejavu because of brain circuit malfunctions

Malfunction can occur between long term circuits and short term circuits in our brain. When the brain digests the surroundings, the information obtained can be directly transferred to the part of the brain that holds long-term memory. This causes us to feel the dejavu, as if we have seen and felt the events we have experienced in the past.

Dejavu because of the rhinal cortex

The part called rhinal cortex in our brain functions to detect familiar feeling. This part may be activated without triggering the work of the hippocampus (the part of the brain that functions as memory). This can explain why when we experience dejavu, we cannot remember exactly when and where we have experienced the same.

Dejavu is more commonly reported by temporal lobe seizure sufferers and epilepsy sufferers. What causes dejavu to occur in normal and healthy individuals is still unknown.
