And I'm In Level 3

After watching a certain movie about going into one's dreams and manipulating them, I kept thinking to myself, maybe this movie is hollywood's way of telling everyone that we really do just live in a dream. Perhaps we are all just sleeping in another dimension and our dreams are this dimension. Think about it, maybe when we die, we wake up to something a lot better or a lot worse, maybe we feel certain pain in these dreams to get us prepared for whatever the hell awaits after it. If you had the choice to go back and change a dream, manipulate it, change the people in them or the events that happened, would you? ... What if you could do this in real life, would our reality just turn into a dream?
