After leaving the first vortex I felt a feeling of sadness and anger come over me. It was subtle at first, but got increasingly tangible as time passed. I felt depressed and upset, though I didn't know why. We went to the next vortex and hiked around for an hour and a half or so. Upon returning to the car I started to feel ill. Waves of nausea came over me and I also felt anxious and weak. I felt ill until we visited an herbalist who gave me various tonics to calm down. He said that I seem to be very sensitive to the energy and my body was overwhelmed.
The whole experience was quite odd, and while I went into the vortex experience a bit skeptical, I came out a believer.
