This topic has been discussed in other threads. I have told this story before. I am a logical rational person by nature. I believe in the scientific method. So when this happened I was at a loss for an explaination.
Okay I have an example that actually pretains to the topic. LOL!
When I was in high school I started dating the sister of a friend of my brothers. (Bear with me it makes sense later). We went on a double date. I was in the back seat with my girlfriend. Her brother was in the front seat with his girlfriend. We had stopped at a secluded spot. My girlfriend stopped and got this strange look on her face. Like something out of a movie. She turned and looked out the back window of the car. She called out her brothers name. He asked what was wrong? She said that an old man was outside and was really skinny. He was coming toward the car and he was dead. Her brother started the car and drove home as fast as he could. He dropped me off at home and I walked in still wondering what had happened. The phone rang and it was my uncle. He told my dad that my grandfather had died. My grandfather had been sick for years and was 6" 1" he weighed under 100 pounds. I asked her about it later. She told me she was born with a tail. ( the end of the spinal cord exposed). It was surgically removed when she was 12. She said she could see when people were going to die or sometimes when someone close to them was going to die. She told me that she knew it was someone close to me and he was trying to tell me something, but she didn't know what it was. When she saw what she saw. I saw a light approaching, but I thought it was a reflection. I have always wondered about how this works? It was impossible to be a coencidance. How did she know?
This isn't exactly a haunting, but it is evidence of life beyond the grave in my opinion.
