There is a wonderful book called Dream Yoga and the Practice of Natural Light written by Chogyam Namkhai Norbu, a Tibetan Buddhist master. While he instructs on developing lucidity and different practices for transcending mental structures (through transformation, dissolution, so on) within dreams, he notes the importance of direct introduction to the natural state.
In a communication with the editor of the book, Dr. Michael Katz, he shared that dreams can generally be sorted by cause and effect that are both gross and subtle, and dreams beyond cause and effect. There are two paths, one that is called dream yoga and practices lucid dreaming for spiritual pursuits, within the realm of cause and effect. The other is beyond cause and effect and is the practice of natural light. He said that the practice of natural light is dependent on receiving a direct introduction into the natural state through a transmission that goes beyond the mind (thought processes and grasping, all mental activity also related to cause and effect). Beyond the mind is the gap between thoughts, and having some sort of experience of awareness that is not ego based, but pure awareness in the moment.
The direct introduction is the actual "dawning of wisdom". Non-dual awareness ultimately liberates us wandering souls from samsara for the benefit of all sentient beings - the Bodhisattvas path.
As an offering to all dreamers, beginning with the article, the dreams that follow are examples of different types of dreams within cause and effect, and a dream that is beyond cause and effect. May all beings have happiness and its cause, be liberated from suffering and its cause, never be separated from the happiness which is free from sorrow, and rest in equanimity free from attachment and aversion.
