How do you know it was the same consciousness doing the perceiving, though? You think because you can remember things that you were also the one that perceived them, but you can take a hard drive and move it from one computer to another and the data is still accessible. It is likely there is no part of you that is fixed, even your consciousness. On the plus side, much like matter and energy, it is unlikely that consciousness is created or destroyed in the operations of the universe. Instead, it just gets reconfigured.
