In one context what you call physical reality is a dream, but in a larger context it is a dream that you have created. When you realize that you form it you come into the memory of your whole self.
And when you realize that you form the events of your life in the same way, you will learn to take hold of your entire consciousness in whatever aspect it shows itself in this life. Through all of this you must realize that you are not powerless. Remember, also, that this life is a dimension of experience and reality even if it is, in contrast, a dream in a higher level of reality in which you have your larger consciousness.
