In this video, by Discovery Science, the potentiality and causes of dream states are throughly examined. "The striking similarity of entheogenic experiences to dream experiences tempts us to seek answers as to whether the benefits of dreaming are potentially linked to the benefits of entheogens. The molecular action of visions produced by dreaming is quite possibly very similar to visions produced by entheogenic drugs. Carefully designed research could lend great insight into the mystery of dreaming, the potential therapeutic value of entheogens, and the potential for neurochemical advances."

The Secrets of Sleep - REM and Dreams links the dream experience to many profound advances humans have been developing in recent years. "Entheogenic drugs and dreams alike have a special place in the evolution of humankind and its value systems. Profound musical inspirations and scientific discoveries of the past century have even been inspired by them. Our ancestors religious views and values were influenced by their faith in visions communicated by entheogenic drugs and dreams. In an age of environmental destruction and moral erosion, the knowledge afforded by dream and entheogen induced visions could not be more valuable. Let us hope that our culture is fortunate enough to open our minds and build on the mysteries our ancestors have explored for ages."
