What was the last sign you received?
Interesting.
It seems that reality presents to our senses many millions of times more information than we are consciously capable of perceiving.
Our brains have many different subconscious mechanisms for chunking this information down to an amount that allows it to generate a model of reality that is presented to our conscious awareness that we get to see as reality.
So it seems that the reality we see (or in any way experience) is not reality itself, but the model that our brains create.
One of the most important parts of the brain’s many mechanisms at work is an area known as the RAS – which seems to be largely responsible for selecting items of interest and relevance from amongst the masses of information coming in.
So it seems entirely probable that most of the time, what is actually happening is that it is the filters of our brain that are changing, that cause changes in the model of reality that our brains make, and direct our attention to aspects of those models. So in this sense, we really do create much of our reality. And in this sense it is referring to the model that we get to experience, rather than the external reality that provides most of the source data that goes into creating the model we experience.
So it is a sort of a yes and no thing.
Yes, on the experiential reality it happens.
No, all experiments I have investigated have shown that it is not happening at the level of objective reality (that which is measured by non aware instruments, rather than by human beings).
