Have you ever experienced a feeling of déjà vu, the strange sensation that you are experiencing something that you have experienced before. An experience that is commonly reported and that puzzled people for centuries. Scientists also call it paramnesia.
What is “Déjà vu”?
The term “déjà vu” comes from French, meaning “already seen” and it was Emile Boirac who imposed that name, although scientifically it is a type of paramnesia. The experience is described as a feeling of familiarity with a place, a situation or a conversation, but not actually experienced before. It feels as if we are reliving a moment we have already experienced.
Déjà vu is a common phenomenon, although it is not entirely clear why it occurs. One popular theory is that déjà vu is a kind of glitch in the memory system. Memory is a complex process that involves encoding, storing and retrieving information. If something interferes with this process, it can cause the sensation that we remember something we never actually experienced.
Another theory is that déjà vu occurs when our brain processes information incorrectly. When our brain processes information, it uses different areas and systems that help us understand what we experience in a certain situation. If something goes wrong in this process, we feel that we are experiencing something we have experienced before.
Is it a positive or negative experience?
It is interesting to note that déjà vu is not necessarily a negative experience. In fact, many people report that they enjoy the sense of familiarity they feel during the episode. However, it is also a puzzling and confusing experience, especially because we do not understand why it occurs.
So how do we scientifically explain paramnesia or déjà vu? One theory is that déjà vu is related to the way the brain stores and retrieves information. When we experience something new, our brain creates a pattern of activity that is associated with that experience. If we experience something similar in the future, our brain “associates” that memory with the previous pattern of activity and causes a sense of familiarity.
Another theory is that déjà vu is related to the way our brain processes time. Our brain has different systems that help us understand and track time. If these systems are out of sync, we feel like we are reliving a moment we experienced before.
Although déjà vu is an interesting phenomenon, there is no clear and definitive explanation as to why it occurs. It is likely that déjà vu is the result of a complex interaction between different systems and processes in the brain. However, as we learn more about neuroscience and psychology, we may gain a more complete understanding of this mysterious phenomenon.
Although we still do not fully understand why it occurs, there are several theories suggesting that déjà vu is related to memory and the brain. As research continues, we may be able to better understand.
