Introduction
Comes over us occasionally, the feeling that what we are doing and saying have been said and done long ago, and the feeling of having been surrounded by the same faces, objects, and circumstances? Only 30 percent of the world population has never experienced Deja vu but, the rest have. I will explain experimental why this happens. Déjà vu is a weird, supernatural feeling of having experienced something that is in fact being experienced for the second time. If we hypothesize that the, understanding is actually of a repeated event, then déjà vu probably occurs because the first, experience was neither fully processed by the brain. Some think Deja vu is a way of your brain trying to tell you something or to give you a message. It’s more of a reaction to the familiar; perhaps we experienced it in a dream before or we’ve experienced it before, because we went through a similar experience beforehand, and your mind links it together so it seems we’ve experienced the exact same thing before. Or maybe our mind pick up something to fast so seem as if you are seeing twice.
Hypothesis
My theory of the scientific clarification of why déjà vu occurs is the human mind picks up a scene to fast. Once you pick the scene up to fast it is stored in the working section of your brain Or the Sensory memory of your brain to represent the image twice. The scene happened before. I will call this theory one and I’ll test it. Based on recent findings in other scientific studies, Studies of the hippocampus (a brain structure crucial to memory), of rapid eye movement (REM) sleep and of a brain wave called theta rhythm suggest that dreaming reflects a essential feature of the processing of memory. In particular, studies of theta rhythm in sub primate animals have provided an evolutionary clue to the meaning of dreams. They appear to be the nightly record of a basic mammalian memory process: the means by which animals form strategies for survival and evaluate current experience in light of those strategies. The survival of this process may explain the meaning of dreams in human beings. This means since animals think about strategies of survival most likely they will use those strategies this could be another possible explanation for déjà vu because the dream is stored in the working memory and never fully remembered but you still have a glance of the memory Enough that when the scène represents it self you can identify the scene. There is also another theory of déjà vu
Brain Activity in Memory
Positron emission tomography (PET) scans reveal brain regions involved in memory. Left, an encoding task (the initial processing of information into memory) activates the left prefrontal cortex. Right, an attempt to retrieve memories activates the right prefrontal cortex.

Simplified Model of Memory
In this information-processing model of memory, information that enters the brain is briefly recorded in sensory memory. If we focus our attention on it, the information may become part of working memory (also called short-term memory), where it can be manipulated and used. Through encoding techniques such as repetition and rehearsal, information may be transferred to long-term memory. Retrieving long-term memories makes them active again in working memory.
Procedure
1 I turn on the TV,
2 I Turn In To a Show I Previously Recorded
3 I get a person to sit in a chair a look directly at the TV
4 While they are looking at the TV I tell them not to take their eyes
Of the TV and I fast-forward it maximum speed to the end.
5 I tell them to close their eyes and think about what they saw.
6 then I tell I will play another provisionally recorded show
7 I don’t fast-forward another show but just rewind the previsoly one
8 I ask them did they see any of the images twice.
9 If they responded no this theory of Déjà vu is false because their mind cant pick up the image to fast. If they say yes this could be a possible explanation for déjà vu.
Theory Two
1 At 5:00 I tap a person and slightly wake them out.
2 I percent and scene and remember exactly what im` wearing I make sure what the room looks like and all the rest of the details.
3 want the person is waken up o percent and image and I say something then I leave the room. (The image was probably presented in the working memory part of the brain or Sensory memory
And they would think it’s a dream)
5 Then At 10:00 I while percent the same exact image.
6 Later on in the day to not make it obvious I will ask the have they ever experience déjà vu and if they say yes I will ask the to discuss about their most recent case of déjà vu .
Results
For theory one the first person said they did not see any of the images twice that could mean they were not focusing on the TV hard enough and really paying The person I test was below age 15 this could be the reason people 15 of age and down according to studies most don’t get deja vu but the second person who was really focusing thought she saw the images twice this was the response I was looking for see she said the word thought the images probably was not fully processed my the brain but once you see the image twice you can relate to it because it was processed partly
