So when I was younger (about 11) my family and I lived in a two bedroom trailer. We had a small little hallway coming from the living room to the main room. My mom is Christian and she listens to a Christian music radio station and we would listen most of the time in car rides (keep this in mind).
In the room I shared with my brother, our feet were pointing towards the door which showed you out to the hallway. If you were to go to the left you would go into the living room and if you'd go to the right to my parents' room.
This one night, I woke up in the middle of the night randomly. I looked up towards my feet and saw a slightly tall man, singing a song I knew I had heard in that radio station before. He just sang and stared at me, but his voice was so beautiful I don't think Zayn or anyone else could sing just like he did (also keep in mind my dad wasn't home at the time, he was in jail).
So the man started walking out into the hallway and walked towards the living room. I was not scared, I was more mystified of the man's presence. I got up and went to my mom and asked her if she had seen the man and she said no and so I explained to her that he was singing the song on the radio station (I don't remember the name or how it sounds). Up to this day I firmly believe that it was an angel watching over my family and I.
My grandma has gone to explain that the way you know it's an angel is if you don't feel anything but peaceful and if it's a demon that you get bad bad chills and are scared to the max.
