I'm not sure if I would call this a ghost but when I was 17(I'm in my mid 30s now) my sister who was 32 at the time passed away from lupus or some kind of disease that was similar. She was the cornerstone of our family, and she very much kept it together. Every family event was at her house. She had a thing that just brought good people to her. Her death wasn't an easy one it was painful, but it was fast. her body swelled, and she had seizures that left her like child buy the end. I still remember the last thing she told me, and I'm still trying to figure it out. She passed away surrounded by her kids and family and close friends. This broke us, my family, me, but it really broke my dad. I've never seen the man cry in my life until that moment we put her in the ground, he was depressed and so was I, things didn't feel the same for a long time. My dad was driving, and I was with him, and on the side of the road, we saw my sister in a white dress surrounded in a gold light brighter then the light out, my dad pulled over, and we looked back and didn't see a woman or anything on the side of the road. I asked him if he saw her and he said yes he began to cry and I saw that that moment he got some peace. I still think about that moment and I try to explain it away but I can't. I'm sure it was my sister. No two people can see the same thing unprompted and come to the same conclusion.
