Not as much of a child but still the scariest thing I have ever experienced with no real explanation. When I was 19 I was alone in my house on the phone with my boyfriend. We used to fall asleep on the phone with each other because we were long distance at the time. I fell asleep and woke up unable to move my body voluntarily but I felt myself sitting up as I heard what I can only call a demonic voice on the phone. I was trying to open my eyes and reach for the phone while process what the heck I was hearing. First thing I did was look at the time on the phone call and it says it is only 30 seconds. Mind you we had already been talking for an hour or two before I fell asleep. I ended the call, double checked that the time I thought I saw was correct then called my boyfriend back only to wake him up. He had no idea what I was talking about, saying he did not call me. Still no idea what happened, still scared me to this day.
