Is this reality or just a dream?

Do we live in a dream world? Is this only a place where we see things that the future holds? Are we someone elses dream? Is someone controlling us without us even knowing? Are we someones robot? Are we programmed to think, walk, eat and drink? Are we really who we think we are?

Have you ever wondered?

We all sit back and think about past events, friends we've lost contact with throughout the years, family who has gone and life as we know it today. But, what if we could go back and change the things in the past; the memories we've lost, the friends who we use to be close to, the family we wish we could have spent more time with. What if we have been living in a world that doesn't really exist? What if this is just a view of our future? Would you change things, or would you just let things be as is?
