I've drank ayahuasca with the Santo Daime church a few times now, and I keep sensing these shadow people walking around behind me. At one point I was sitting in a chair, and I was struggling trying to find the right page of the hymn book and deal with this energy ripping through me at the same time, then a shadow man comes up behind me and drops a seed in my head. Somehow I could see the whole process, like I was watching myself from behind. Trippy stuff. I'm new to ayahuasca, so I was too preoccupied with everything going on around me (like the fact there was a picture of a bearded Brazilian guy on the table, who had patterns emanating from his beard which were warping the fabric of reality) to pay much attention to these shadow people, but in retrospect, I'm pretty fascinated by them. They seemed busy doing things in the background but what exactly, I didn't know.
