I woudn't hesitate to use one and I do believe things like that are real since I am known to "knowing" things myself. Ever since I was a child, I just "know" things, usually about my family members, that something bad is going to happen. I have had a horriable feeling of dread since the Christmas holidays that something bad was going to happen to someone in my sisters family Then that happened to Brandon....... That was just the most recent.
