Saw an angel?

I have been trying to meet my angel or spiritual guide for a few months through meditation. I thought I got a name, David during one of my meditations. Also, my psychic teacher in my psychic development class told me that my angel's name is Gabriel. However, she didnt see his physical form. A few days ago, I gave Reiki to my mother. Before I did the healing, I sent a thought to the angel of healing to overlight my healing. During the healing, with my eyes closed, I saw in my mind's eye a white figure behind me. She was wearing a white robe and her features are very beautiful. Could she be my guardian angel? Or is she the Angel of Healing? She doesn't have wings. Does that mean she is something else? Any ideas?

My Reiki master told me that there are Reiki angels. I think you saw her.
