Reiki healing

Anyone here familiar with reiki healing? I had my first session done last week and during it I experienced something strange. Aside from the colors I saw, which I assume is common, I saw a woman. While I was laying there with my eyes closed I saw from brown skin woman with bright red hair. It was only from her chest up and she was like whistling or doing some movement like that with her mouth. She stayed a few long minutes then disappeared and I went back to seeing the colors. I asked the healer and she told me to look into it lol she’s a beginner and wasn’t sure what I saw.
