Tall Thin Angels

When I was 23 years old, I was alone in my house, and decided to take a nap. Before I went to sleep I heard whispering so I looked next to me and two very tall thin angels were standing back to back, as if they were saying something about me, because they were looking at me too. It lasted for a few seconds. when they noticed I saw them they disapeared. They were almost transparent, but very plain to see, one was taller, and had dark hair, about shoulder length. one was a little shorter, he had blond hair. it will always be a slight mystery to me, I think they are my real angels who thinking I was asleep, were checking in on me. It makes me feel safe to know this.
