Buddhism explains that a conscious mind is active during the day and a lonely mind is dreaming at night. When dreaming, most of them are creating their own lonely shadow realm, where it is really sad and happy. Sometimes the seeds of the eight senses appear, and you will see some past and future things. So dreams are mainly your own business, not arranged by others. But sometimes I dream special dreams with the will of Buddha and Bodhisattva or the karma of other sentient beings.
