"My 21 yr. old son died in an accident in our own yard in May 2007.  A few days later I was in the basement (where he and his friends always hung out). It was evening and something caught my eye in the reflection of the window.  When I did a double-take and looked again, I saw not my own reflection, but that of my smiling son with is head full of curls standing there with his favorite hat on.  I turned around quickly, but there was no one behind me.  Shortly after that on numerous occasions, I smelled marijuana as I descended the stairs into the basement.  My son and his friends occasionally smuggled one into the house and I would warn them "not inside the house".  By the time I got to the bottom of the stairs, the smell had faded.  My brother experienced this same sensation when he was looking for something on my son's workbench.  My daughter and I often heard his bedroom door close, but when we went to investigate, found it wide open and nothing disturbed.  Our son's kitten would sit at the top of the steps and look down as if he could see someone.  We also heard my son's heavy work boots on the stairs many times, just as we had when he was alive.  There were other incidents as well.  I often felt his presence in the basement.  These things went on for many months, then suddenly stopped. My son loved life and one moment of carelessness cost him his life.  He was not finished here on earth and that's why I think he continued to hang around for so long.  I honestly don't think he knew he had died.  My heart still aches for my only son, but I like to think he is finally at peace"
