Perception of the world we’re living in?
You might think: "What does hypnosis and our ability to see have in common?" Well, it's a part of our reality perception, and you'll learn here that not everything that we see is necessarily correct. I am very passionate about the mechanics of our reality and the way we perceive it. I want to share this with you.
I think we can all come to a conclusion that a main tool of our perception is our vision. But is this vision real, or is it some kind of illusion?
"Seeing is believing" is a common adage widely used in our society. But is this really true? Can we believe what we see? Let’s have a look at the simplified mechanics of our vision.
Our ability to see depends on light and that is quite obvious. Not only do we need light, but it has to be in a specific spectrum. We already know, that the human eye can see only light between 390 and 700 nm of the light spectrum. Everything before and beyond that wavelength is not visible to us.
The light bounces from the object we look at and enters the eyes through our pupils. The pupils function as the lenses, similar to a photographic camera, and they literally focus the image and project it at the eye’s retina. At this stage, the image is actually upside down and at this point, we are not able to see anything yet.
The image projected on the retina gets to be converted into electric signals and neuron pathways delivering these signals to the visual section of our brain which is located at the back of our head. Here the electric signals get converted by our brain back to the image of the object we're looking at.
To be able to do that, our brain needs to search memories of our sub conscious mind and look for the information which will match the image. Without that information, the brain wouldn’t be able to recognise what we are actually looking at.
You remember the first time you fed your child some grapes? You put it in the child's mouth and they said: "It's a grape...yum" The child ate the grape, and through his/her senses experienced what the grape looked like, felt like, smelt like and tasted like. All that data was stored in the subconscious mind for later retrieval. Since that moment, the child knows what the grape is.
But let’s go back to the mechanics of our vision and perception. In reality, what we see are actually only electric signals, which our brain translates into an image.
At this point, we have to realise that our brain is kept in absolute darkness, provided by the protection of our skull. If we look at a burning candle, in reality the light the candle emits will physically never reach our brain, but we can still see the candle’s flame in its full colour.
The same applies for all our senses, because their signals are processed exactly in the same manner as our sight is. What this means is that our brain is never in touch with our outside world, but instead it will create for us some kind of electronic copy of it. That brings up the question: Is what we see real? And if yes, to what degree and how our perception affects experience of our reality ?
The scientific fact is that we can see only a fraction of the light spectrum. We’re unable to see the rest of the spectrum. However, because we can’t see it, it does not mean that it doesn’t exist. There are realities in other spectrums, and we're even able to see some of them, provided we use an appropriate technology, like for example infra-red night vision goggles. So it appears that the old adage “Seeing is believing” looks a bit shaky.
The same vision principle would apply in reverse. If we break the connection of an optic nerve, as in the sample above, obviously we would stop seeing. But regardless of this, that image would still remain in our reality.
By now, we can see that our perception of reality is solely created by electric signals in our brain. However, if this is the case, how can we be sure that the perception created this way is real and correct?
We can compare our brain to a computer’s hard drive, basically because it is a storage device filled with data. It contains the data of all our life experiences. At the time of birth, this storage device is almost empty as it contains only basic instructions on how to keep our body alive. Everything else is learnt through life's journey.
All those learnt experiences become the building blocks of our belief system. This sets our belief system to function as some kind of filter through which we see and perceive our life.
