From what I've read (and I havent read much) these STME's sound like they're quite simple, and I've read similar by robert monroe about astral traveling. for them its more like playing.

I need to find a good source of dmt and find out myself! I'm in brisbane, Australia, and I'm kinda figuring about the easiest source might be Queensland silver wattle. Looks like I have to do some exploring!
