That is a question I think about too, and I am pretty sure I would want get out of the matrix.

If you want to change your perspective of existance dramatically and metaphorically "step out of the matrix" for real, I suggest looking into the philisophical writing of david hume. He answers a lot of questions about what makes a certain individual an individual and bases all that we view as reality as the accumulation of data through the senses. Reality to him is a seris of cause and effect relationships between what we percieve and the combination of those observable cause and effects with our memory to create a sense of individuality. Its quite interesting stuff, and I am not sure if my brief and sloppy explanation makes any sense, so you may want to check him out for yourself.

*Warning* his book (Treatise of Human Nature) is written in a style that is pretty unusual and therefor difficult to understand, and it is a little long and boring at times, so if you dont think you have the discipline to force yourself to read his actual book, at least research the points he makes on the internet. It really is interesting stuff and essentially the basis for the theory of natural selection which is the current champion in the world of theories for the origin of man.
