A few days ago, I had a terrible, horrific dream. In it, my 9-year-old son was badly injured. I thought he was dead at first. Without going into graphic detail of what was a very vivid, realistic image in my mind, I awoke just as my boy began to open his eyes.
It stuck with me all weekend. It's still with me right now. It scared the hell out of me.
