Unification Aspects:

A dream is the experience of a sequence of images, sounds, ideas, emotions, or other sensations during sleep. The events of dreams are often impossible, or unlikely to occur, in physical reality: they are also outside the control of the dreamer. People all over the world throughout history have experienced and reported dreams, yet dreams remain one of the most puzzling aspects of consciousness that humankind possesses. Both religion and science have tried to define what dreams are, where they come from, and what they mean.

Some have been, or believed to have been, prophetic, messages from the spiritual world or heaven giving warnings or announcements of fortune that is to come. For some, dreams are seen as manifestations of our unconscious desires, thoughts, secrets that we repress in our waking lives but which surface as we sleep. For others, a more straightforward and benign explanation is that the brain processes the experiences of the day into long-term memory during sleep, sometimes activating a stream of data into consciousness, forming a dream.

Unification Thought explains that human beings consist not only of body and mind, but also an eternal spirit. If not for the Fall of Man at the beginning of human history, all people would be aware of their spiritual senses and be able to communicate with the spiritual world during their earthly life in the body. However, for most the spiritual senses are dulled to such an extent that many deny their existence. Dreams, or at least some dreams for there are many types of dreams that have different purposes, are one way that spiritual beings, and God, can communicate with us, albeit imperfectly. Thus we should take note of the content of our dreams, for it may contain important messages, such as that given to Joseph to protect Mary when she became pregnant with Jesus. However, setting too much store by dreams as opposed to the "reality" of the physical world has its dangers. Not all dreams are from God or heaven; Satan and evil spirits may also influence us through our dreams. Achieving maturity as a human being, united in mind and body, may prove necessary to be able to discern the source and true meaning of dreams.
