Megan Fox and Machine Gun Kelly went on quite a trip while in Costa Rica.

The “Jennifer’s Body” star revealed on “Jimmy Kimmel Live!” on Monday that the couple flew to Central America to drink ayahuasca, a psychoactive tea, in “a proper setting, with indigenous people.” The experience induces auditory and visual hallucinations and is said to treat various ailments like anxiety, trauma and more.

Fox explained they went to a location known for catering to celebrities looking to go on a spiritual journey but discovered it was just the remote jungle.

“So I was thinking it was like glamping, like it was gonna be some kind of five-star experience,” she quipped.

“But 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,” Fox recalled. “There was nothing glamorous about it, and it’s all a part of making you vulnerable, so you sort of surrender to the experience.”

Fox explained the ceremony began with the group, which included about 20 other people, vomiting up the contents of their stomach by drinking lemongrass tea.

“And you 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,” she said of the experience, admitting that she and the “Bloody Valentine” rapper were skeptical of throwing up in front of strangers until they realized it was “such a good bonding experience.”

The former “Transformers” star said the ceremony lasts three nights but on her second night she went to Hell for eternity in a hallucination.

 “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 shared.

Fox, 35, said the experience surpassed 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.”

“So it’s your own version of hell, and I was definitely there,” Fox added.
