All the information is light. As long as light rays reach our eyes in a certain angle, they represent things in our three-dimensional space. But what if something distorts it? What if some surface reflecting those rays also distort them, just like the reflection of everything on the water? What if our perception of reality is also distorted with some entity that hides itself at a deeper level from the foundations of our consciousness? How can then we say with 100% confidence that what we see is what there really is out there? Can you really believe in your eyes when you know that there is no way for you to perceive reality as it’s out there in the first place? But… is there a reality out there anyway? Isn’t all reality the sum of the experience of all the collective consciousness of all of us in the end? Does it really matter?
