Voice Singing

I was in my teens or early twenties, it was in December I woke up in the middle of the night. I sat up in my bed and I heard a deep, rich, voice singing, Christmas songs. I checked the radio, and television, but they were off. At the time I didn't think it was an angel singing to me. That voice was all around me I recall. The years have passed and I believe it was an angel. But why me? I thank God for that special moment.
