Two years ago at Burning Man, Andrea tripped on ayahuasca and had visions of herself as a woman in a past life. At the time, Andrea, a 33-year-old transgender woman, identified as a man, but she had struggled with gender dysphoria since high school. “Growing up I had no transgender role models, and there was nobody to tell me that what I felt was something anyone else had,” she says. “I was unhappy with how I was living, and I really wished I had been born with a female body.”
