Whats the point in having a younger self if the original person's(the matrix ) mind doesnt transfer to the younger self to experience everything the younger one goes through. When they switch the one that is sleeping has no idea what happened to the other. The writer really messed up in the most important part of the plot in why the older self would want to create a younger self seperate of her. Which is to experience her youth all over again. Terrible execution of strory creation!!
