It can be analytical, judgmental or therapeutic in nature. We all have dreams that are confusing, filled with images and events that do not always make sense to us. We spend hours trying to figure them out, and often end up frustrated when we fail at our attempts to decipher them. The manifest content is the dream as it is remembered - what happened, where you were, who was in it, what you were doing, etc. It may be sensible or full of nonsense.
Dreams are full of symbolism.
Symbols are very important in religion, especially in primal religion. Religious symbols are the mediators in religions between the finite and the infinite, the profane and the holy. Primal religions place symbolic meaning to almost everything. The symbolist vision sees the things of the world as transparent to their divine source. Symbols are important in all aspects of life and are not to be ignored.
