10 Intriguing Theories Explaining Déjà vu
Déjà vu is a rare occurrence, but we know when we experience it.
We are convinced that we have lived the moment before.
And often, it almost feels like we can predict what is going to happen next!
But, that bizarre feeling goes away as quickly as it came, and we’re back to our normal
reality.
The actual cause of déjà vu has yet to be confirmed by science.
However, dozens of theories have been proposed trying to explain this strange phenomenon.
Here are 10 of the most fascinating and thought-provoking examples!
Number One: Familiarity-Based Recognition
When we recognize a stimulus in our environment, we are using our “recognition memory”
which has two forms: familiarity and recollection.
Recollection memory is when we recall seeing something which we have seen before.
Familiarity-based recognition happens when we believe we are seeing something we recognize,
but have no memory of it actually happening before.
This could mean that déjà vu occurs when we have a faint memory of something that already
happened, but the memory is not strong enough for us to recall where we remember it from.
Number Two: Senses and Memory Mix-Up
This theory tries to explain déjà vu by linking it to our sensory perspectives.
According to research, our memory is context dependent.
This helps to explain déjà vu by showing how stimuli in the environment can easily
provoke a memory.
A certain sight or smell may trigger our subconscious mind to recall a time when we saw or heard
the same thing.
Number Three: Dual Processing
This is another theory that involves memory acting incorrectly or using higher processing.
This theory suggests that when we perceive something, our brain is simultaneously trying
to encode a new memory into our long-term memory.
Thereby creating the illusion that we have experienced it before.
This momentary timing error could be due to a tiny malfunction in the brain that is rather
common to us all.
Number Four: Parallel Universe
This theory claims that déjà vu can be explained by the feeling of having lived a moment before
as a “crossover” with a parallel universe.
Meaning, that whatever you’re doing while experiencing the déjà vu, a parallel version
of you is doing it in a different universe simultaneously - creating an alignment between
the two universes!
Number Five: The Hologram
This theory is the idea that our memories are formed like three-dimensional images.
Which means that they have a structured frame network to them.
This suggests that the entire formation of a memory can be reconstructed by one element.
Therefore, if one stimulus in our environment reminds us of a previous moment we have experienced,
our brain makes a connection to the past event and produces a “hologram” of the memory
to make it feel like we are reliving it.
Number Six: Precognitive Dreams
This theory explains déjà vu by suggesting that the moment we have the experience of
living something before, is when we have previously dreamed about the present happenings.
For example, you may have a dream about riding your bike on a certain road, and then later
you ride your bike on the same road as the one in your dream.
You have a precognitive recollection of the road which allows you to recognize it.
As dreaming is not a conscious process, this explains why we don’t consciously recognize
the stimulus yet still feel that it is familiar – such as the road in this case.
Number Seven: Amygdala
The amygdala is a small section of our brain that is responsible for our fear response
to things in our environment.
The amygdala can be used to explain déjà vu - if we consider the moment as a temporary
brain malfunction.
If we are placed in a situation that is almost the same as a situation we have been in before
but it is changed somehow, our amygdala can produce a panic response.
It puts us in a temporary state of confusion, and this could be our experience of déjà
vu.
Number Eight: Divided Attention
This theory suggests that déjà vu occurs due to a subliminal recognition of the object
in our experience.
This means that our subconscious mind recalls the stimulus, but our conscious mind does
not.
In which case, déjà vu could be the recognition of a message we have received subconsciously.
Believers of this theory presume that subconscious messages can be communicated to us through
sources such as the Internet, television, and social media.
Number Nine: Reincarnation
Reincarnation is based on having several lifetimes before we were born into this life, with no
recollection of the previous ones.
This theory explains the experience of déjà vu by referring to the moment as a signal
from a previous life.
There could be a trigger in the environment which allows the transition of consciousness
to occur.
Such as recognizing a certain stimulus from a previous existence and momentarily remembering
a past life.
Number Ten: A Glitch In Reality
This theory describes déjà vu as a momentary breakdown in our reality and suggests that
time doesn’t exist; it’s only a made-up convention to establish order and structure.
What we believe to be the past, present, and future are actually all happening simultaneously.
Therefore, when déjà vu occurs, we are simply slipping into a greater level of consciousness,
where we are able to live more than one experience - at the same time.
What do you think?
Which of these theories sounds like the most possible explanation of déjà vu?
