It is a good viewpoint to see the world as a dream. When you have something like a nightmare, you will wake up and tell yourself that it was only a dream. It is said that the world we live in is not a bit different from this.
Had I the heavens' embroidered cloths, Enwrought with golden and silver light, The blue and the dim and the dark cloths Of night and light and the half-light, I would spread the cloths under your feet: But I, being poor, have only my dreams; I have spread my dreams under your feet; Tread softly because you tread on my dreams.
