What is déjà vu and how does it feel?
Déjà vu is a strange mental experience where a person feels like they have already lived through a situation, even though they know it is happening for the first time. The term comes from French and it means “already seen.” (4)
According to Encyclopaedia Britannica, déjà vu is described as a false sense of familiarity that happens in a completely new situation. It can last only a few seconds but some people say it may linger for longer. (1) It often feels very real and can be slightly confusing or even have you pause for a second to think ” have I ever been in a situation like this or not?”
Many people describe déjà vu as a strong feeling of recognition, like a moment or place is familiar, but they cannot explain why. For example, someone might walk into a room for the first time but feel like they have been there before. Even though they know it is new, their brain creates a sense of familiarity.
Websites explains that this feeling may happen when the brain mistakenly matches a current situation with a memory that is very similar, even if it is not actually the same experience. (2) So it’s really like a “glitch” in the brain. Your brain creates the illusion that the moment has happened before.
Déjà vu is usually very brief and not harmful, it’s just a weird or unsettling feeling that happens for a few seconds. Most people experience it at some point in their lives, and it is more common in younger people. (3)
