The fear of being buried, embalmed or cremated alive, is it irrational?
Depends on where you live. In the U.S. the fear is irrational because: 1) should you die in a hospital, your generally connected to devices thea can detect the slightest signs of life, long before you would be turned over to the undertaker for embalming and 2) Should you die outside a hospital without a doctor in attendance, The medical examiner is usually required by law to perform a post-portem (after death) examination, and quite often an autopsy to determine cause of death. Again this would happen long before the body is released for embalming or cremation. I can’t speak for what might happen outside of the United States.
I have a variation of this fear. I combine fear of death with claustrophobia. Although I have tried, I can’t seem to shake this irrational fear that I’ll actually still be alive after death, and stuck inside my dead body. The fear is that you, me, and everybody who is ever going to lie in a coffin will actually be semi-alive down there, unable to move, and just stuck there, day upon day upon day, with nothing to do, no one to talk to, but aware, alert, and it never ends. This fear makes no sense, but I have not been able to get rid of it.
