Universe that is created controlled by you where you are also the subject. Game that you create where you control the universe the environment and the parameters based on your perceptions of the world and people you interact with. Again where you are also the primary player who is either viewing the game play where other players are playing in the environment you created or your viewing yourself in 3rd person where you respond to the world that is created by yourself.

The way you respond to the environment are a particular situation in the dream is based on your perception of yourself the way you would react and the way the environment or the people you see in your dream respond. Everything including you the way you behave the the way the world response and other people respond or all your own projections. Since your also the one who is viewing the dream the interactions between different parties can happen at a much faster pace then it can happen in the real world. I think this could be one of the reasons that the pace of activities in your dreams how much faster than they happen in the real world. Probably anything that doesn't provide much feet back to you and which are like since elements or activities have an at a much faster pace then something that provides you more inputs. For example let us say that you want to go from a to point b in your dream unless there is some from your understanding that needs to be projected along the way this even is going to be a much faster one where in you imagine you are starting from your home and you are going to office. The whole activity can happen in just a couple of seconds provided that there are no not for the events that happen during the travel.
