Are there any rational arguments for.......?

I suppose one could say that reality is simply the aculation of people's individual perspective taken from their own experiences as well as societal norms, values and beliefs. In this sense, everyone has there own version of reality in which no two realities are the same. Because of different experiences, cultural values, etc, there is no one set of reality that can be conveyed throughout the entire universe because reality itself is merely a creation of the individual. Therefore reality exists in a person's own mind meaning that reality does not exist as an outside force. In other words people create reality, reality is not constant.
