This may be a slightly more common fear that people have because of all the horror stories about people who were actually buried alive. I'm just scared that I'll be placed in a coffin and left underground to slowly suffocate and there will be no escape because you can't push the coffin lid up.
So I've decided that if I am to be buried, I will be buried with a phone or a button I can press which will alert people that I am indeed alive and need saving.
