I have read the article. Thanks for sharing. I do believe that interacting with entities encountered in DMT trips is possible, but never experienced this myself.
Perhaps it all depends on one’s intention. Entities must feel that the person is open to it. For me DMT is pure fun and unbelievably exciting. It is looking through a window and seeing those bizarre higher dimensions. Until now I have not seen any experience as therapeutic, healing, interacting or what ever. Curiosity is my driving force. I am only observing.
Keep on doing your research
