A few years back, I had a reiki session and found the experience quite strange. As I left the appointment, I felt nauseous and ended up throwing up. At this point, I put this down to somethin I ate. However, my wife had a reiki session last night and when she arrived home she was very pale, her head was very sore on the left hand side and she was throwing up. The headache started when she was having the reiki session and the practioner advised that this can happen. Can someone explain why we both have experienced side effects like this?
