I know how you feel.....
I used to live with my brother in Las Vegas, NV. He had bought a 26 year old (4 years ago) house on the northeast side of town. Anyway, when we moved in, the house seemed fine, a little dark, but fine. Well, my brother worked nights, so I used to be in the house alone all night long.
Anyway, one night I was reading a book in the living room when I heard my name being called from the other room. Mind you, NO ONE was home at the time, just me. I ignored it and continued to read. Then out of no where I heard my name again, but this time the sound came from right behind my ear! It was a man's voice, but I didn't recognize it.
I also experienced other wierd things in that house!
