The meaning of Know / knowledge in dream | Dream interpretation
Spiritual knowledge and awareness can develop gradually.
If we are prepared to allow it, this knowledge can come intuitively through dreams.
Psychological / emotional perspective: In dreams we often know something without being sure of how we do. Many believe that in the dream state we have easier access to the collective unconscious – the repository of all knowledge – than when we are awake.
Material aspects: In mundane terms knowledge and experience go hand in hand. In dreams the mind may trigger an association, which allows us to reach viable conclusions.
