This took place in the mid-'60s in my teenage years in Wetumka, Oklahoma. My cousin, in her early 20s and married only two years, lost her husband in tragic car accident. He had a construction job about 200 miles away and would drive home for the weekends, leaving on Friday.
One Friday on his way home, he picked up a hitchhiker and ask him to drive since he was getting sleeply, so the hitchhiker agreed and started driving. My cousin said the Highway Patrol figured the hitchhiker dozed off and ran off the road. Her husband's car door opened and he fell out and the rear tire crushed his head. This resulted in a closed-coffin funeral. The funeral was held at our church, which is next to Wetumka Lake, and there is long blacktop to get there.
After the funeral, my mom asked Sylvania if she would like to come spend a few weeks with us to get her bearings, and she did. The first Saturday at breakfast, she told us a story about a dream her husband had told two weeks before his death at breakfast. He told her in this dream that he was walking down this long blacktop road and came to a lake. He heard singing, so he followed the singing and came to a church with lots of cars and lots of people standing outside the church. He went inside and saw a beautiful blue coffin that had the lid closed, so he couldn't see whose funeral it was. He also saw Sylvania dressed in black, looking very sad, like she had been crying. He wondered whose funeral it was, then he woke up.
After telling us her story, Sylvania said he had seen his own funeral. Yes, the coffin was blue.
