I am fascinated by this stuff and DMT and part of me would love to try it. It appears most people experience the same entities such as the self-transforming elf machines. I read another transcript where somebody met their intergalactic girlfriend and the absolute bliss of their reunion and how it felt like they have known each other for hundreds of years.
