Making noise during Ayahuasca ceremony

Someone on fb posted that they always roar all through ayahuasca ceremonies. They are unaware of it but it apparently goes on all ceremony. There was some back and forth on the issue, and I finally decided to weigh in on it. This was my comment:
If people are deep in the medicine and begin to make noise, whatever it might be, I always allow it for a few minutes because I don't want to interfere with their process. But once it becomes problematic--is taking over the space--I try to get them to walk out of the ceremony space with one of my team and walk them to the edge of the protected area, facing away from the ceremony hut, where they, under the eye of one of my team, may sing, dance, roar, scream, do whatever they like or whatever they are being compelled to do by the medicine running through them. But I do not let them stay in the ceremonial space and take over for a long period. I explain beforehand what the protocol will be and that the experience is not a participatory one: People came to the Amazon for the trips to hear the curandero sing, not to hear someone rebirthing. But I don't ever want to have people feel they cannot do what's necessary. They just can't do it in the ceremony hut. But outside, facing the forest away from the hut, they are welcome to do what they need for as long as they need. And always under the watchful eye of one of my team.
