Actress Megan Fox told Arsenio Hall, who was guest-hosting for Monday night’s “Jimmy Kimmel Live”, about her recent experience drinking the hallucinogenic tea ayahuasca. Fox was on a trip with her boyfriend Machine Gun Kelly in Costa Rica where they tried the psychoactive tea in the wilderness with “indigenous people.”

“So we went to Costa Rica to do ayahuasca in, like, a proper setting, with indigenous people” Fox explains to Arsenio Hall. Allegedly the group that gave them the tea drinking experience is known for taking celebrities and high-profile people on ayahuasca journeys.

Fox said the experience was intense, lasting three days, and took her on a spiritual journey that rivaled therapy and hypnotherapy. “You get there and you really are in the middle of the jungle, and you don’t get to eat after like 1 p.m. You have to walk a very far distance to get your water, and you can’t shower because they’re in a drought” added Fox.

“There was nothing glamorous about it, and it’s all a part of making you vulnerable, so you sort of surrender to the experience” she added. The second night of her journey she says she was taken to her own version of hell for eternity. “Just knowing it’s eternity is torture in itself, because there’s no beginning, middle or end. So you have a real ego death” she explained.

The actress says the journey helped her understand more about herself and said it “surpasses talk therapy or hypnotherapy…because it just goes straight into your soul, and it takes you to the psychological prison that you hold yourself in.”

As part of the “journey” Fox described how participants “all line up at the edge of the rainforest, over this weird fence, and you go here by three and you drink lemongrass tea until you, no by your own volition, just vomit everything out of your body.” You also “have to vomit a certain amount until they let you get back with everyone else, so you’re like cheering on everyone as they throw up.”
