We don't live in reality, or even "see" it directly.
The reality that we live in is firstly based on perception of actual physical reality, and then also experienced/conceptualized via a proxy, which is a model of our perceived reality (and all the objects, people, and ideas within it), all implemented by a sophisticated biological neural network of sorts.
An example of how you can test this theory is to observe conversations on forums, where you will find plentiful (and ultra-confident) examples of supernatural acts like mind reading, future predicting, knowing things that are not knowable, etc.
Even more interestingly, these "beliefs" seem to be entrenched extremely deeply in the human psyche, and almost "protected" in some way, by some sort of process. Merely pointing out the obvious fact (the existence of this phenomenon) is highly unpopular. But even further, most people seem to be literally unable to even ponder the phenomenon, particularly in real-time. Abstract discussion seems much easier for most people, but rare is the person who can consistently walk the talk - personally, I only have one friend who can do it, across multiple domains (cross-domain capability is a key differentiator that separates those who can from those who cannot).
