Heathen: I prefer that people stay on topic of which is about ghost stories
Sorry, but stirring up fundamentalists has always been an irresistible temptation for me. But I do have a ghost story for you. Like most true ghost stories, it's not scary at all and actually fairly mundane. In fact, I'm pretty sure it was just a flight of imagination, but here goes...
When I was 14 my great uncle, who was legally blind, drove off a cliff with my great aunt in the driver's seat. My uncle walked away with some minor injuries, but my aunt ended up in a coma. I visited her in the hospital the following day and, while her condition had seemed to have stabilized, the doctor didn't know if she would ever wake up.There wasn't anything to do, so we left the hospital.
On our way home, my mom and I stopped at Walmart to pick up some groceries and when I was walking through the aisles I distinctly saw someone who looked exactly like my aunt. To my surprise, she made eye contact with me, smiled and said she loved me but she was dead, then literally vanished before my eyes. I dismissed it as a hallucination until we got home and found a message on our answering machine. It was the hospital. Apparently my aunt had died while we made our way home.
While this had a strong emotional impact at the time, looking back I think it was probably a hallucination brought on by stress. If she had died instantly after the accident and appeared to me before I even knew anything, I would be less skeptical. Still, I suppose it could have been her.
