Tales from a Skeptic: My Grandfather's Death

I grew up in the Christian church, but these days, I lean agnostic, which my atheist sister says is basically "Atheism without the balls." As a lapsed Christian with family who has passed, sometimes I do crave a deeper meaning or proof of the afterlife, but I don't really believe in ghosts or the paranormal. My father's family is very logical, and my paternal grandparents have both requested no funerals and little fanfare, because they don't believe there is a hereafter and think funerals are in poor taste.

My mother's family is a different story. They are Vietnamese immigrants whose traditions are steeped in superstition. My grandmother's brother was a fortune teller, and my aunts, uncles, and cousins have had their fortunes (the good and bad) told by him. They are surprisingly accurate. My mother claims she requested to not have my sister's and my fortunes told because she (sometimes) believes you make your own luck and having a "bad" fortune can prejudice the person to that future. Anyways, my grandfather received a fortune saying that he was destined to die in the presence of only one of his children.

On the day of his death, he was driving his three-year-old daughter, my Aunt "Sarah," to the store. When he was turning left, he accidentally hit the acceleration instead of the brakes, and hit a post. Sarah wasn't wearing a seat belt, but grandfather held out his arm to prevent her from going through the windshield. She ended up breaking her legs. Grandfather hit the steering wheel (no airbags), and died instantly. They weren't far from home (only a couple blocks), so the older children who heard the commotion ran to the site of the car accident. My grandmother was hysterical. Even though she was three, Sarah remembers the details of this day because her mother always asked her what she remembered and she would repeat everything. She wondered why her mom always wanted to hear the details anyway. When Sarah was in high school, her mother finally told her. In the aftermath of the accident, she held Sarah and asked her what happened. Sarah, who spoke broken Vietnamese, looked at her mother and said in fluent Vietnamese, "I went somewhere and saw Grandma. Grandma told me I had to come back here and to tell you what happened. She tore my pants to let you know she sent me back." Grandma saw that her pants were torn and asked her to repeat what she had said, but by that time, Sarah had forgotten about seeing her dead grandmother. Grandma keeps asking Sarah throughout the years, hoping that she will recall the episode.

This is the last experience I have that fits in this subreddit. I really don't know what to believe. It wasn't until I was writing the last post about the Ouija board that I even realized it. By all accounts, my grandfather had an extremely bad temper, and he spoke five languages, including perfect French.
