The more influential the person, the more careful he has to be in this regard. Since Moshe missed an opportunity as the leader to bring the people to greater heights of spiritual awareness, he lost the privilege of being the leader. There's another reason Moshe was denied entrance into the Promised Land. That is to enable dispersion when the people of Israel sin, because Moshe symbolizes eternity, as the Torah he passed on is eternal. If he would have brought the people of Israel into the promised land they would never have been exiled from it, and when they sinned they would have been destroyed, G-d forbid, instead of dispersed among the nations.
Dreams are the buds of prophecy.
This is indeed a wonderful metaphor, for just as a bud is the actual fruit itself that has not yet developed fully, similarly, the power of the imagination at the time of sleep is exactly that which operates at the time of prophecy, in an incomplete and unperfected state. Therefore dreams, which have their source in ratzon, because they are of the world of freewill, are one sixtieth of prophecy which is from the world of netzach. However, the first one is fulfilling a mitzvah d'oraita, a Torah commandment, and the second one is transgressing an issur d'oraita, a Torah prohibition. And I say that as a non-Jew who reflects the feelings and sense of amazement provided by Tolstoy and Mark Twain. Thank you for the great amount of courage you display in this secular world, which continues to denigrate the sacredness of being Jewish.
