And what does that mean, friend?
the subconscious mind is heavily influenced by dreams. the subconscious mind also has a heavy influence ON dreams.
the subconscious mind and the CONSCIOUS mind are interconnected. they're more than interconnected they are dual aspects of a SINGULAR consciousness imho
and the conscious mind is obviously of one the main factors in the progression of one's personal evolution.
and bringing it back full circle, writing dreams down helps you remember them, and thus the mental/emotional lessons learned from that particular dream.
dreams are spiritual training.
