As dream yogis develop familiarity with astral projection, dream recall, and awakening consciousness, there remains the difficulty of interpreting experiences. Practitioners must know how to discriminate what they perceive, the spiritually real from the illusory ego, through three spiritual parameters: Imagination (perceiving a dream), Inspiration (recognizing dream symbols), and Intuition (comprehending their meaning).  

Since divinity communicates through the language of parables, interpreting dreams also requires a profound, practical understanding of the cosmic laws upon which they are based: philosophical and contrary analogies, correspondences, and numerology. By meditating upon these factors in combination with the psychological impression of a dream, one acquires insight into its significance.
