Fountain-like vomiting during ceremony — what does it mean?

Hi everyone,

I’d like to ask something to those with more experience. During one ceremony I witnessed something quite intense — a person started vomiting like a fountain, very forcefully, and at the same time he was making deep, growling sounds.

I’ve only seen this happen once, and it looked very different from the usual purging. Does this have any particular meaning from a traditional Amazonian perspective, or is there a physiological explanation for this kind of reaction?

I’d really appreciate any insights 🙏
