That is so creepy....what a jerk! Did the voice sound like your ex? I worry I'm being watched because some azzhole on social media wrote me some stuff that made it sound like I was and he had "tapes" of me. It was really unsettling but I've come to accept it as possible and not worthy of stressing since I can't change it. I also think I'm being watched by those who have passed on.....usually it's a pleasant feeling but one particular person was sinister when living so when I get the feeling they are around it's not good at all.
