It is a good viewpoint to see the world as a dream. When you have 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.
Everyone, when they are young, knows what their destiny is. At that point in their lives, everything is clear and everything is possible. They are not afraid to dream, and to yearn for everything they would like to see happen to them in their lives.

All Nature seems at work. Slugs leave their lair - The bees are stirring - birds are on the wing - And Winter slumbering in the open air, Wears on his smiling face a dream of Spring! And I the while, the sole unbusy thing, Nor honey make nor pair, nor build, nor sing.
Happiness in this world, when it comes, comes incidentally. Make it the object of pursuit, and it leads us on a wild-goose chase, and is never attained. Follow some other object, and very possibly we may find that we have caught happiness without dreaming of it.
