I think that "reality" as humans percieve it is different than Reality. What we view to be "reality" seems to me to be a very limited and sometimes scrambled image of Reality.
To try to explain my views in a very...simplistic way:
First, our most fundamental understanding of Reality comes from our five senses. The information that our senses collect is handed over to our intellect (which analyzes it, draws conclusions, stores data away for later) and our subconscious/unconsicious mind (which translates the part of Reality we are able to sense into symbols and stores it away in that form).
It is easiest to understand how limited our perception may be by imagining reality if we took away some of our most basic senses. Imagine what reality would seem like without a sense of smell, eyesight, sense of touch, hearing, or a sense of taste. It would be very different.
Now imagine some of the senses other creatures have that we do not. What would our reality be like if we could see ultraviolet light as bees can? What if our hearing and sense of smell were more acute, like that of a dog? What if we could hear and make sounds way below the range of human hearing like giraffes can, or hear sounds above our range, like dogs? Think of the world from a bat's point of view, or a snake's. Their realities are just as valid as ours is, and in many ways are both more and less limited... and all very different.
Which reality is the right one? None... they all depend on what the senses can detect of Reality, but none are able to sense Reality in its completeness.
Now think... we have an idea of the senses of other creatures because, in many cases, they are very similar to our own. We can hear, just not in the same way as a giraffe, bat, or dog can. We can smell, just not like a dog or a snake. We can see, just not the way a bee can. But what if there are simply things out there that we CANNOT sense... and neither can any other creatures on this planet... because we simply have no means of sensing it? Not only would we not have this sense ourselves, but we would not even know that it exists, and without the ability to detect things with this sense, would would also not even know if they exist, or understand their full nature.
I admit that this is highly doubtful... surely if these things exist they could affect us in some way... the lack of understanding would be a handicap that evolutionarily we would have eventually overcome... but what if they do exist? What if they simply do NOT affect us, and therefore we are unable to detect them? If so, if they DO exist, then that is part of reality that we are unable to percieve, unable even to simply comprehend.
