Does A Split Reality Exist?

Does A Split Reality Exist?

Déjà vu as a failure of the brain to put "time stamps" on memories.

Where or When (Words by Lorenz Hart, Music by Richard Rogers)

When you are awake; The things you think come from the dreams you dream; Thought has wings-; And lots of things- are seldom what they seem; Sometimes you think you have lived before; All that you live today.; Things you do – come back to you,; As though they knew the way.; Oh, the tricks your mind can play!; It seems we stood and talked like this before.; We looked at each other in the same way then; But I can’t remember where or when.; The clothes you’re wearing are the clothes you wore.; The smile you are smiling you were smiling then,,; But I can’t remember where or when.; Some things happen for the first time,; Seem to be happening again - ; And so it seems that we have met before, and laughed before and loved before,; But who knows where or when!

It happens to many people – you are there and it’s as if you have already been there, you know what is going to happen next and it seems a part of another life you have lived. Some claim that déjà vu is signifying problems in your mental state, that you are probably losing your mind and start living in the hallucinating world of a person with mental problems. Others accept it as a fact of life. But in a survey, over 80% of the participants who reported having experienced déjà vu, denied a possibly clinical condition before their déjà vu incidents, such as mental and physical fatigue, depression, stress, anger, fear. And surveys among random groups of population show that nearly all people experience déjà vu. The statistics varies from 30% to 96%. (3)

The concept of déjà vu is not very well studied. Even though a common phenomenon, most of the studies have concentrated on clinical populations such as psychopathological patients. (6) Neppe’s definition describes déjà vu as any subjectively inappropriate impression of familiarity of the present experience with an undefined past. (2)The term "already seen" was first used in 1876 by E.Letter Boirac who called it "la sensation du déjà vu." In 1896 F.L. Arnaud introduced it to science. (7)Many researchers are cautious when dealing with instances of déjà vu because of the chance the person who experienced the sensation may have read or seen something that is in his unconsciousness triggering the impression.
