My step dad died in 2002 (I don't remember the dates but I do remember it was in 2002), after he died I was really sad and I started sleeping on the couch in our living room and at night, I would watch tv. We had two computers on the other side of the living room. One was his and a week after his death, when I was trying to sleep, I could hear a cough (he had heart problems and diabetes) and the clicking of a keyboard and when I looked over at the computer I saw like a bluish outline of him. Other than that, I could hear sounds of bags (like chip bags) rustling and when I checked, no one was there, but I could still hear it. My old cat Tornado, who disappeared, really liked my step dad and after he died (my step dad died in his and my mom's bedroom) Tornado would NEVER go in that room again and when I went in there for about a month, it was always really cold. What was strange was I could hear it as if he were still alive, but I could still see him as clear as day (I knew I was awake because I spilled some milk on my shirt the first night and it was there in the morning). I asked everyone but no one else could see him or hear him.
After about 2 months, it stopped completely.
I just thought I'd share my story. Thanks
