INTRODUCTION
What is real? How do you define real? If you're talking about what you can hear, what you can smell, taste and feel, then real is simply electrical signals interpreted by your brain.  - Morpheus (The Matrix)

1.It was my own belief next coming decade word virtual will be a very common to everyone since we all living in margin of real world and virtual world (Kind of dream world). When I started my high school studies in mathematics concept of imaginary numbers make me so confused but thought of its real existence me more confused. When I looked through a mirror I always thought imaginary world which was explained to me in complex numbers are exist inside the world that I am observing through a mirror. 2.When I was a kid TV show “Star Trek” and “Blake’s 7” induced my desire to study about Teleportation (term that refers to a number of theories and notions concerning the transfer of matter from one point to another without traversing the physical space between them, similar to the concept “apport”, an earlier word used in the context of spiritualism).

Further my desire to learn concepts of Holography and Virtual Reality (VR) was stimulated due to two popular movies “Total Recall” and “Matrix”. 3.To day scientist had found that everything we experience in life can be reduced to electrical activity stimulating our brains as our sensory organs deliver information about the external world. This interpretation is what we consider to be "reality." In this sense, the brain is reality. Everything you see, hear, feel, taste and smell is an interpretation of what's outside, and created entirely inside your head. We tend to believe that this interpretation matches very closely to the external world. Nothing could be further from the truth.

4.It is the brain that "sees", and in some important ways what it sees does not reflect the information it derives from sensory input. For this reason, we are all living in our own reality simulations - abstractions - that we construct as a result of both what we perceive with our senses and how our brains modify this perception. Such things as color, smell and taste, for example are not properties of the outside world itself, but rather a category created by the process of perception. In order to experience the world in a meaningful way, the brain must act as a filter/interference between us and the "real" world.

5.Words have always been a crude method of relaying intent. VR holds out the promise of allowing us to literally show one another what we mean rather than merely describing it with crude verbal approximations. The limitation of words is that the meaning they convey is only as detailed as the definitions the reader or listener attaches to them. For this reason VR offers the possibility of evolving our communication into a kind of telepathy, ultimately bridging the gap between our discrete imaginations. "This is what virtual reality holds out to us - the possibility of walking into the constructs of the imagination." - Terence McKenna

6.VR is the ultimate medium of syntactical intent; the only way to figuratively "show" someone exactly what you mean is to literally show them. Words are exceptionally ineffective at conveying meaning, as they are a low-bandwidth, lossy medium of knowledge transference. VR will let us remove the ambiguity that is the discrepancy between our internal dictionaries and bypass communication through symbolism altogether. The result will be perfect understanding, as...
