Before I go on I would like to inform the "OP" that there are several legal drugs that you can take to alter your reality, and to get a better understanding of what you are truly asking yourself.
Reality is a result of the human process of evolution. Yes, it is a fact that we evolve, and anyone who says otherwise is just merely living in a "delusional" reality. We don't live, and we don't die. However, we do observe consciously. Yes, we are born, and one day we will die, but that's based on our very own observation. Reality really isn't any one persons own thing because it changes for everyone at it's own pace. Have you ever lossed someone close to you due to death at a young age? Your reality will change if that has been the case.
Someone who once could see, and has now become blind due to some parasite, disease, or near fatal accident will tell you their reality has changed. Realities change even without negative, or traumatic experiences as well. Many people all over the world are married in love, and happiness each day. Those realities are changing for all of those people. Even with that said reality is something we can barely put a true definition to. We are living within an infinite consciousness that has infinite measurables. Your brain recognizes these realities, and thus your conscious being ( the soul) holds those realities forever. We are immortal sir, and so in essence we have probably had this conversation in some form, or another like a billion times, or more.
