Another aspect of this for mental health is that it is possible to experience the common "machine elves" that people encounter. I am as skeptical as it gets but I'm really not sure if I've encountered beings from some other dimension or if my own mind is capable of the weird, sometimes horrifying, always profound shit that I've seen. The first Ayahuasca trip I went on I immediately had intense hallucinations of the feminine spirits. They put out their hands and invited me to walk with them. As we were walking down some kind of hall I reminded myself that these beings were easily a creation of my mind, that we do this kind of thing all the time in our sleep. As I was entertaining this thought one of them violently turned around and yelled "NO". The other being, in a sad voice I'll never forget, asked me why I felt the need to reduce and explain away the experience. I think about this often.
