Some interesting observations I've noticed about people's heavy DMT reports, where they met the "machine elves". (very likely demons in their natural realm)

There seems to be a trend with creatures encountered nightmarishly harassing people until they submit, and perhaps related I've heard reports of these beings bouncing in and out of people, changing them "fixing". There's also reports of people coming back very different and seemingly given a purpose on earth. They eat healthier and are basically "on a mission from the dmt creatures". If you don't submit, you come back with a bad trip and heavy trauma. These are definitely not good creatures by in large. Lots of reports of people getting sliced up, etc.
