i agree... but it is an old idea already... in Journey to Ixtlan, by Carlos Castaneda, we read that the world of everyday life is not real, or out there, but only a description of the world. "Everyone who comes in contact with a children is a teacher who incessantly describes the world to him, until the moment when the child is capable of percieving the world as it is described"
so, our notion of world is just one (of many anothers) way to percieve it. but as we only know this way, we think it is the "real". I strongly suggest to read this book. its great and have many enlightening ideas about the nature of reality, world and life.
