Received call from this number today that was quite terrifying. Caller actually asked for me by my last name. I didn't identify myself to the caller and when I asked him who it was that I was speaking to he said to me, "I am your worst nightmare." I asked again what his name was and he said again, "I am your worst nightmare, Mr. ****." I then told him, "I don't understand who you are." and he said, "I am the sleepy time ghost that comes to you in the night and gives you bad dreams." I hung up.
