I feel you want to believe that this entity was your guardian angel. And, what is wrong if it was the spirit of a deceased person?
It could be that it was your Reiki guide...... what does it matter who it was? The important thing is that you had the presence of spirit helping you in healing that other person. I don't think the healee should be so fussy in accepting or rejecting who helps you and them in the healing process.
If you want to believe the other entity was your guardian angel, then so be it. I also believe what spiritalk said about angels in our life appearing to us in the form of living beings.
Are we now being fussy as to who comes in to our aid in time of need? It is a blessing, so let us welcome them, as long as they are of higher level spirit entities and not lower level entities.
