Obviously. Indigenous people who have been working with plant medicines for thousands of years (medicine people) understand all of reality to be a dream, and the physical dreaming state to be nothing less but the travel of one's spirit away from one's body, which results in the expansion of one's awareness.

Good to see progress in connecting what has been understood forever through experience with physical analysis, one must however not be fooled into thinking that one will understand anything about plant medicines by analyzing their physical effects -- what happens here starts on a much deeper level.
