Not everything you see is the way you see it as It's just a very narrow perspective of what is really before you. I'm not saying that the part you see isn't real to you, however, the tools we have to interact with the world around us is very limited while for others it's different but still as limited so we see things similar but not the same as we are two different aspects with things like history that can affect how we see objects.
You can see an object in a different color as another person because they way your mind interacts with that object can vary from your history, genetics, space, to name only a few of probabilities that can change the perception of the world around you. If you should live but a moment let it be your last as each day pass as you may never know what fate holds.
