In real life, when we are doing a particular thing, often have a sense of deja vu.This seems everyone will appear, then what does that mean?In ancient times, in the absence of theory, this kind of situation will be using the principle of "to people without dream" to explain, "to people without dream" dream and reality have no objection, we both live in the dream and life in reality.According to my personal understanding, is the reality and dreams, just as we often say the impact of space and time.Dreams and reality is two equivalent time, compared the dream to the future, as the present reality, then the collision of space and time when dreams and reality overlap, will let us have the feeling of deja vu.

"Deja vu" and actually we used to say "think, night dream", there is a correlation relationship.According to the theory of modern science to explain the "deja vu" and "thought, night dream" mainly can be divided into two aspects.

The first: theoretical explanation.

"Deja vu" is our stand in the Angle of the real life to experience the dream do, and think more nights dream "" day" is the idea is we know through dreams to reality.Their relationship is opposite and associated.Instead because of misleading role "deja vu" is a dream to reality, and "thought, night dream" is the dream lure subconscious appear in reality.

In both cases, happens relationship with our brain can't open.The brain in a certain period of time or a certain time of visual memory disorder happens.Reserves have a special memory in the brain, when we see in real life or in the dream or meet one thing, the brain will be to cache memory this passage, when we when I'm doing a similar thing, the brain will be fetched a memory area, and then give us a feeling of deja vu, will let us have predicted such ridiculous ideas.

The second: stress.

In life because of the pressure hallucinating incalculable consequences have a lot of news.So "deja vu" and "day thought night somewhat dream" also has relations with the pressures in real life."Deja vu" is caused by real life pressure, the cerebral cortex to produce a subconscious activities, some of the things that have no experience, fiction and brain will this imaginary things as a memory cache.Then one day in real life to do something similar to the imaginary things memory in the brain, and the role of psychological pressure, would mislead us to produce the feeling of deja vu.

"Day think more nights dream" because in real life to generate ideas and has a certain thing and pressure, the pressure may be the result may be outside your own factors.So caused by this matter make you escape the psychological pressure, and because the power of the subconscious mind, make we can't ignore the source of this pressure will make us use it in a different way, also is the dream we used to say.So they formed a "day think more nights dream".

"Deja vu" there is a lack of scientific explanation."Deja vu" is a function of time and space changes or memory of the dream.Because of the role of space and time, will be at a certain time will happen in the dream, but because influenced by time and space, we this period of memory blurred.So when the real time with the time to achieve a common dream, the brain will be active to this period of release affected by time and space and vague memory, cause we produce "deja vu".

Each human has endless desires and wishes, but because of the influence of the reality, that we have to store these desires to use another way, when holding a warehouse full of desire, and will pass in a different way to the desire to achieve, this is called "day, night dream".

"Deja vu" or "day think more night dream" because of pressure, but this does not affect our health, as long as the brain in a healthy person can produce this kind of situation.But in order to prevent the occurrence of this kind of situation too much, make our existing way of the dream and the reality of alienation.You need to learn to bear stress and emotions in your own mind, reduce the pressure on the brain and nerve function, makes them keep relaxing in the rest.
