Why do we all have an individual way see things?

The idea of the ultimate reality that is the same for everybody is a myth. The reality is different for everybody in the world. How we see things depends on the experiences that we have. The same thing that might mean funny and pleasure to some people might be very traumatic for some other people. We know that things like festivals and concerts are meant to be places, where everybody has fun. 

But some negative experiences can cause that person ever go to those places. The fact is that feelings are in dominating role in the way to see things. The fact is that if the person has some kind of difference in the nervous system or senses that can cause that person to see the world differently than others. So when we are thinking of observation, we must realize that memories have a big influence to things how we are seeing things. 

This thing should show that people are individuals. We might see things differently than other people. We might have an allergy that makes something like a chocolate painful experience. That thing causes immune system over-reaction and the itch. This itch makes that very common tasteful candy a bad experience for others. 

This is one point of seeing things. When we have some kind of anomaly that thing changes our way to see things.
