Dream Yoga or Milam the Yoga of the Dream State are a suite of advanced tantric sadhana of the entwined Mantrayana lineages of Dzogchen (Nyingmapa, Ngagpa, Mahasiddha, Kagyu and Bönpo). Dream Yoga are tantric processes and techniques within the trance Bardos of Dream and Sleep and are advanced practices of Yoga Nidra. Aspects of Dream Yoga sadhana are subsumed within the practice suite of the Six Yogas of Naropa. Düsum Khyenpa, the First Karmapa, realised the 'absolute siddhi' of bodhi (Sanskrit) at the age of 50 whilst engaged in Dream Yoga sadhana. In a footnote on 'Zhitro' Namdak & Dixey, et al. (2002: p. 124) identify that the 'dream body' and the 'bardo body' is the 'vision body' : In the bardo one has...the yilu, the vision body (yid, consciousness; lus, body). It is the same as the body of dreams, the mind body."
