Déjà vu is a French phrase that means “already seen.” It is a common experience in which a person feels that they have already witnessed a new situation or event. Déjà vu can be a fleeting feeling, or it can be so intense that it feels like a real memory. Why does it feel like this? Is there anything we should know about this?
There is no scientific consensus on what causes déjà vu. However, there are a number of theories. One theory is that déjà vu is caused by a glitch in the brain’s memory system. This glitch could cause a new experience to be mistakenly registered as a memory. Theory #2 is that déjà vu is caused by a split-second delay in the brain’s processing of information. This delay could cause a person to experience the same event twice, once in real time and once as a delayed memory.
Theory #3 is the most interesting theory. It is the theory that déjà vu is caused by a brief glimpse into the future. This theory is supported by the fact that déjà vu experiences often involve events that are about to happen, such as a conversation that is about to take place or a turn that is about to be made in a road. Could there be a way to harness your future memories? Probably not, but it’s a very thought-provoking concept.
We can sometimes recall having a dream with the exact same events taking place there, as it has in reality. If this was the case, it would mean that there’s more to the conscious mind that we don’t understand (which is already a fact). It is a strange phenomena, that still needs more elaborate and innovative research done on it. It’s stunned scientists and philosophers for centuries, and is a reminder how truly complex the human brain is.
