While taking shower, I always come up with dozens of interesting thoughts.
Recently, I have come up with the idea of colors and the way we perceive everything might be different..
What if the way we perceive colors is completely different. The way I perceive red and others might be different. Maybe, other people perceive red as blue and I perceive red as white.
There might be people who perceive the color of blood as black, white, blue but they think it is red because it is how they taught to be.
Of course there is no way to prove it but if you think deeply about it, it is crazy.
