A good dream is no good
The purpose of Vedic study is to transcend the activities of the three modes of material nature. Of course in the material world the mode of goodness is accepted as the best, and one can be promoted to the higher planetary systems by being on the sattva-guna platform. However, that is not perfection. One must come to the conclusion that even the sattva-guna platform is also not good. One may dream that he has become a king with a good family. wife and children, but immediately at the end of that dream he comes to the conclusion that it is false. Similarly, all kinds of material happiness are undesirable for a person who wants spiritual salvation. If a person does not come to the conclusion that he has nothing to do with any kind of material happiness, he cannot come to the platform of understanding the Absolute Truth.
