If you become attached to the Buddha in your dream, it is natural that you are destined to cherish it, but such a dream can only show that you are attached to the Buddha, so you should learn more about the three treasures and learn more about the Buddha. Then such a dream won't appear again. Everyone is blessed by buddhas and bodhisattvas, so there is no need to be afraid of ghosts. What are the three difficulties of repaying four benefits and helping the poor? Others, hungry ghosts and regions are suffering. Why should we be afraid? We should be merciful, feel their pain, read amitabha for them, and hope that they will go out of their misery and go to the western paradise. Both the answers upstairs are correct.
