A childhood belief about people

After the death of my great-grandmother (when I was about 6), my mother was trying to explain to me what happened to people after they died. Not having any specific religious views other than a belief in an afterlife of some kind, I was told "nobody really knows what happens to the soul", which for some reason satisfied me. I was more upset about what happened to the body. When I was informed that the body was put into "a casket", I must have got "casket" and "basket" mixed up, because I pictured dead people getting stuffed into something like a clothes hamper, which was always called the "laundry basket" in our house. I thought that was horrible. I didn't sort it out until several years later, when I saw a funeral in a movie.
