I've heard voices too. Only they came from inside my head. I'd be almost asleep or maybe I was asleep. I do have DID or MPD. Anyway a few times it sounded like my mother and she was mad at me. Other times it was just a female voice and it would feel like they were trying to get my attention for what ever reason. All the voices would ever say is my name.
One time I had a voice that seemed to come from the corner of the of the room up high. It seemed to me it was my grandmother, my father's mom( who passed away in the 70's). I felt like a little girl ( I was in my 40's) again and what she said scared the crap out of me. "So, you perceive to know something devil's spawn?" Perceive? Just seemed an odd word for anyone in my family to use. Devil's Spawn? Creepy!!!!
