Have you ever got weird telephone calls

Some other weird things happened in Sept 1999 in Atlanta. Once in the evening I was starting to sleep and suddenly I started feeling strange pain in my chest, almost like a heart attack, and I received a voice telling ‘if you do not take that fax, you’ll die’. I had a small home office in the house where I lived and then after few seconds receiving this voice, I heard that a fax was being sent to my fax machine. I got up and went to get this fax, it was from the Society of Competitive Intelligence Professionals, and so I got a fax and did not die. These have just been some real experiences long time ago.
